dyno tuning - 1999 turbo low 9 sec 4.8 Silverado 808whp

[@JasonLeaman]

I miss those days where sloppy would go out and drive a truck with power and leave parallel lines and smoke all over the city :( bring this back !!

[@SloppyMechanics]

i can work on that!

[@wobblysauce]

Every day is Icecream day.

[@Stevesbe]

It's like he's becoming an old man Lol

[@The980Junior]

He IS alive!!! My Seven year old last week said, “Dad does Matt do videos anymore?” He’s enjoyed 8f8 and dyno videos. Keep you the great work

[@Mattvardaman]

Love it when the 4.8 makes big power. They sound awesome at 7000 rpm.

[@JoeSimpsonAtTempest]

Perfect something to watch on the way home from the track

[@CORZER0]

Thing is solid! No shake, wobble, rock, nothing, just solid.

[@stroomperformance]

Hell yeah I'm excited to see this. I just put a camaro together with a similar setup, the only difference is I have a 5.3. So I guess we'll see what happens with mine

[@richardpenner4686]

Love the dyno days...love the nerdy stuff to..keep it coming..

[@jasonn4397]

Always love these, thanks Matt

[@ianm432]

What a good looking truck. Killer power.

[@slowfox89]

Another informative video. It's appreciated.

[@Jvaughan1989]

Love a good late night upload!!

[@randalblack518]

It has Bob horsepower..... I love it

[@S4Meow]

Look at you, getting fancy with chapters! Nice truck.

[@beaugouin4383]

Love it!! Ghost is parked today after cracking homemade log on beer run. I was down on power… lol! Slop style!! Love truck builds!

[@philbetthauser9547]

Impressive build ‼️

[@808redneckify]

Sexy truck should have continued the black theme and tint the windows. Not sure if I love this truck more than the colorado. 🤔

[@JosePineda-ce4bk]

Any info on the hot side of the truck? Just your usual truck setup or?

[@GTStuning-]

Hi, do you know if his Jegs converter is the 3200-3500 stall like the "higher stall jegs" converter on your wiki page? I ask as they also have an XHD in 3500-3800 and 3800-4100 stall. I'm after a similar power goal so just asking to possibly avoid blowing through the converter.

[@SloppyMechanics]

Unsure

[@ze_german2921]

Basic question here: How do you change your boost so quickly from 10psi to 26? is the waste gate spring being changed every time or is it being adjusted from the cockpit electronically with a switch?

[@SloppyMechanics]

electronically controlled, i did a video called "comprehensive boost control class" and it goes over all the better known ways to control boost from simple mechanical to c02 based twin solenoids check it out!

[@1989GTADRIVER]

Luv these videos!!! Great build!!! 👍 And enjoy the radio stuff too

[@bryanleverett2830]

Did “this old Tony” edit this video? Lol

[@mauricewaddelliii6244]

This gives me hope seeing my turbo z71 makes mid 800s on “low boost” that I can click off 9s

[@stivic923]

I remember this truck from earlier this year. Wasn't it like a gen 3 4.8 th400 s480 terminator x? Something like that

[@SloppyMechanics]

Yes

[@nathanboyles6222]

@@SloppyMechanics i assume its gen 4 rods, cam and valve springs?

[@TravYFZ]

noice!

[@ochoabraham8]

How do you get that many Rpm’s on my 5.3 I hear is not good over 6-6.2k rpm’s

[@codyfoster7574]

Is there a mod list or anything

[@nitrouscatfish5827]

We need engine bay shots mott

[@bigj7807]

Could he take it to 1000 hp? With that setup

[@dj_laundry_list]

Why is the truck lowered it is intended for drag racing? Did they want worse weight transfer or something?

[@04droppedsilvy]

This isn't always true. My truck dropped on a 4/6 transfers great..better than stock trucks. I think like everything it depends on the quality of parts and shocks. No front sway on mine though. My truck is nowhere near the power of this truck though. Caltracs are always an option too.

[@bigj7807]

Is this one hitting the tune cabinet ???

[@SloppyMechanics]

it is too similar to many others to post small variations of the same tunes on the cabinet imo, there are many very similar to this, if you guys insist i can post this exact file

[@grabasandwich]

🤯

[@Red-eb1wu]

Hey Matt how do I contact you about tuning my 1980 Malibu 6.0 4l80 terminator x swap?

[@SloppyMechanics]

Email [e-mail]

[@vagabond3045]

If I sent u my specs could u do a tune for me I’m not computer savvy

[@ehworkshop9922]

Seems regulator issue its not running 1 to 1

[@tylersmith2874]

Plz put this tune in the tune cabinet

Is this tune in the tune cabinet? just curious, I have the same setup

[@kevingarrett118]

Are any of the tunes that you can download for holley HP?

[@SloppyMechanics]

@@kevingarrett118 iirc there are some, mostly you can copy over 99% of a tuneup back and forth the software is identical

[@derrickgolden4864]

@@SloppyMechanics That be awesome please!!

[@jaimeestrada4507]

What was the ethanol content?

[@SloppyMechanics]

i would have to check logs but its usually 60-78 ish for pump

[@champspec]

I assume this was on E85, but you’re at 12.0 AFR?!?? Was your O2 sensor just set up for gas?

[@IceTrey98c]

yes its e85, thats about standard afr for ethanol.

[@jamieknight9636]

Great job, thx

This truck is a bad bitch
