Stock Chevy Silverado 1500HD 6.0 Dyno

[@kozmicflush980]

The cateye silverados are truly the most beautiful trucks built by man. These year models are the last of a generation when men and women actually worked and put blood sweat & tears into their craft. With the 1500 HD, you got yourself a rare one. Keep it, forever!

[@samuelyi9189]

Thank you for the in depth detailed video! I’m about to take my 03 1500HD 4x4 with only 135k miles on it to the dyno in two weeks or so. The fuel enrichment god. So that explains why it feels like it’s “lugging” when you really want it to get up and go

[@chrishansen7004]

I find that the best mod you can make to these older 4 speed trucks is a gear swap, look into a gear vendors you can run 5.13 gears and your highway rpms would be the same as the 4.10s without the gear vendors it's really cool stuff and really brings an old 4 speed up too par with the new trucks especially a 4L80 considering how long first gear is

[@Red-b1r8i]

But you can't have a 4x4 right? There is not enough space and you have to deal with the transfer case.

[@Benmendoza1]

Love the Parkway Drive intro! Lol!

My 05 2500hd with an aluminium 6.0, shaved 243s, flat tops, tsp stage 3 low lift, tbss manifold, 30lb injectors, long tubes and full exhaust put down 308/314 on a mustanh dyno I have 34" mud terrains and 20 inch wheels but wow, one of us has some wrong numbers.

[@TonyTheTruckGuy]

I'm certain mine were skewed high for some reason, although I'm also certain that the 34" MT's are hurting you haha. Your numbers sound much more believable.

[@alexanderromo1313]

Your plate has GMT in it that’s really cool

[@TonyTheTruckGuy]

Lmao, right? Funny thing is I never even found out about the whole GMT thing until maybe a year ago haha. Always just called them a cat eye or “angry headlight” style lol

[@DavidToyotaHead13]

Really makes me wonder what mine puts down. I tuned it myself via HP tuners, timings around 22-23 degrees with zero knock and timing adders zeroed out, added a ton of fuel (using a Wide Band to tune WOT) and have it dialed at 12.5 or .85 lambda at WOT, through a NV4500. It surprises me for being a 6500 lb truck.

[@TonyTheTruckGuy]

Yeah unfortunately this truck will be getting sold to fund some other projects for now but I want another one some day to cam and turbo lol

[@marco_zamudio3832]

i recently took my 2000 silverado 4.8 ext to get a dyno tune. I prevousily dyno it and i made 251 hp and 180 torque. after i got it tuned, just having a cold air intake it was able to push 287hp and 270 torque. keep it in mind i paid 400 for the tune and it had 230,950 miles on it.

[@TonyTheTruckGuy]

Yeah man the 4.8 is great. 230k? Perfect for boost lol

[@marco_zamudio3832]

@@TonyTheTruckGuy I was surprised and so was my tuner. Now I'm just want to run nitrous on it but I have no clue how much hp it can resist without having any issues

I have a 2017 Silverado 6.0 3500 and modified my tune with HP tuners. Dropped about 3 sec off 0-60 and I can now spin my 33s whenever I want.. worth it

[@TonyTheTruckGuy]

It’s amazing how much throttle lag and torque reduction they have on the factory tunes haha

[@Thejohnnyoshow]

this is exactly what i was looking for i have a 2500hd 2001 lq4 6.0l with 33" tires and it runs pretty solid (very very good actually for 180k) so i would say its probably safe to say i would be close to the same power other then i have a brand new wix filter and dual muffler/exhaust but not strait pipe

My thoughts also, but 100 hp is a huge difference lol.

[@Elcompajuanpablo]

Thanks for spoiling it😢

[@masl2004]

Our trucks are pretty much identical. Mine has a cutoff exhaust currently, thanks to a friend, but I have the stock filter.

[@canamcartel9694]

Sweet truck i love these years.Those crank values are closer to 50% not 20%. But thats a good gain in power for some tuning. Makes me wanna take my 01hd in for a tune. But once i start searching for power its hard for me to stop. Lol.

[@TonyTheTruckGuy]

It wasn’t even really a “tune”, he just removed the speed governor and turned up that “fuel enrichment” so the injectors would actually spray 100% when commanded. It’s still the stock tune file otherwise!

[@davestewart9146]

Always cool to see 👍😁

[@jeremylakenes6859]

Did this affect your gas mileage? I mean, more fuel seems like it would be less mileage, but if you don’t need to mash the gas and wait for rpms it seems like it would help.

[@TonyTheTruckGuy]

Didn’t seem to affect it from what I can tell. She’s always been thirsty haha. I get like 11 mpg no matter what.

[@vhp454]

The factory air box is actually more efficient than the so called cold (hot) air filter assembly.

[@TonyTheTruckGuy]

@@vhp454 Yeah I wish it had the stock air box when I got it

[@kefwals8722]

Gm has always low rated their hp numbers up until probably recently. It was notorious when you see the specs on the GNX and other vehicles after the 70s gas crisis. So it's not surprising if the 300hp flywheel being lower than actual hp

[@TonyTheTruckGuy]

I’m just surprised it would be off by that much haha. It just sounds too good to be true, but I’ll take it.

[@jacobvanhalteren7452]

@@TonyTheTruckGuy pretty sure they were rated 300 - 330hp 340 - 360 ft lbs

those corrected numbers have to be off because 303 x 1.20 assuming 20% loss is 363.6, but still very good for a stock motor

[@dnvr12]

20% loss isnt a guarantee for all vehicles. Some may be 18 some may be 19 some may be 20…

[@bradbuss3026]

Question for you. Do you still have that truck? I see you're from Minnesota. Wondering about the reliability of it. I'm actually looking at buying one same year.

[@TonyTheTruckGuy]

I do! Needs some TLC that I have to address and might be selling it next year after that but this generation Silverado is my favorite. They have a few quirks like all vehicles, but overall very capable and dependable trucks without all of today's overly expensive electronics. The key is finding one not rusted in half by now lol.

[@jacobvanhalteren7452]

Gets me excited to build my 6L, aiming for 450 whp and 450 w trq. gonna go with a TSP stage 2. have you cammed the truck yet?

[@TonyTheTruckGuy]

No I’m spread thin on money right now so this project has unfortunately been paused. Would love a cam and low boost turbo combo though with similar wheel horsepower numbers to what you’re looking for.

[@kozmicflush980]

I have the 1500HD (2003) but 2WD. With a level kit, do you think i can fit 33/12.50 M/T wrapped in 20x9 0 offset with no major rub issues? Unfortunately for me, with the 2wd train my only options are level kit, 3 inch lift or the big 6 inch.

[@TonyTheTruckGuy]

I think you will probably rub. My buddy had a 4x4 2001 Sierra with 2” level and his 33x11 all terrains rubbed his mud flaps on stock wheels. You’re going to be sticking out even farther with a wider tire and 2wd sits lower than 4x4. Even these tires on this truck rubbed on the front bumper lower balance before doing some trimming and they’re only like a 31.5 or 32” tall tire. Not sure on wheel specs though as these were on the truck when I bought it.

[@kozmicflush980]

@@TonyTheTruckGuy I will most likely have to settle with the 6 inch lift then. I wish the 4 inch were available for 2wd, to save a bit of cash. I. definitely don't wanna worry about rubbing, and with M/t it would be bad even with a Norcal trim it seems. Thanks for your response! Hard to get a reply on youtube with Truck guys so big thanks, brother!

[@jesseparadis6141]

Can u post or tell me exactly what he put your settings at so i can tell my tuner to do the same thanks man

[@TonyTheTruckGuy]

Not sure exactly what all specific parameters he set, all I know is he used HP Tuners and went under the “power enrichment” tab and then changed the rpm at which it gives full fuel. That and removed my speed limiter.

[@billyjack8119]

Did you dyno it with the new cam yet?

Not yet unfortunately, too busy with life and other projects lol

I’m not really hearing what you’re talking about but you may be just hearing the tire noise on the dyno rollers in the video.

[@stangvrtch22]

have you done the cam swap yet?

Negative. I've got some small stuff going on with the truck but mostly maintenance and cosmetic upgrades/repairs currently. Recently got a motorcycle and a cammed Pontiac G8, so money has been tight lol.

[@alexayala6720]

What kind of size wheels and tires you have ???

[@TonyTheTruckGuy]

I bought it like this so I'm not 100% on wheel specs but they seem to be 16x8, but I'm not sure on offset. Truck is actually at my buddy's place so I can do some work in his shop and I can't remember exact tire size, but I believe it is a 265/75R16. Wider than stock and slightly taller. I think I saw 2 other questions you had but maybe they got deleted or something. MPG has not been changed noticeably since the fuel enrichment change. I get about 10-12 mpg when empty no matter what and slightly less while towing lol. I know you said you were in CA, but I'm not sure if the fuel enrichment counts as tuning or not in terms of CARB issues. I'd Google performance shops around you and contact them to ask. The fuel enrichment is just allowing the engine to get full fuel when it wants it, it's not actually changing the tune MAP or anything, so I could see it going either way in CA. Better to ask the pros that tune for a living.

[@RC-mo8tl]

Have you towed with it any since tuning? Any improvement?

[@TonyTheTruckGuy]

No, honestly I haven’t really towed anything with it yet since I got it, just hauled a few things around I’m the bed. It didn’t get an actual full tune, he just messed with that fuel enrichment. The difference is very small, but it’s there.

[@RC-mo8tl]

@@TonyTheTruckGuy gotcha. I am gonna remove the PE and PE delay from mine, was wondering how big of a difference it makes.

[@TonyTheTruckGuy]

@@RC-mo8tl Per the dyno, about 30 hp and 60 tq, but it doesn’t feel like that much on the street. A full tune would likely do more though, especially if the trans gets tuned as well. This is a good starting point though.

@@TonyTheTruckGuy good to know. I think a 60tq bump would really help me towing on the interstate.
