Dyno tuning a PROCHARGED and BTR CAMMED 6.2L Denali!

[@B.O.T.S-Detailing]

Dig the long videos. Love indepth explainations even if you've said it 20 times before.

[@blknbrwn]

Only true motorheads understand the valve Matt gives in these videos. Greatly appreciate the content!

[@promobass77]

Thank you so much! You're wasting your time trying to help us, ordinary people without that kind of experience. This is very valuable information! You are a very cool dude!🤙🤙🤙🤙🤙

[@andywatson-mo1jr]

I really like the longer more in depth videos. Awesome in depth as usual. Thanks Matt.

[@CPoston420]

Love the long vids, Im just starting to tinker w HP Tuners, learning a lot

[@Lunatikgixxer]

I agree i love the long videos too. Awesome vids

[@Art-nc1mw]

You got your self a subscriber with your in depth analysis. Great work!

[@scottprimeau9325]

Thanks again for the time you put into your videos!

[@mattl1576]

Matt-thank you for taking the time to put these videos out. Very informative and has got me interested in learning how to tune. Looking at purchasing a MPVI3 very soon.

[@wisky3]

Perfect timing, I have the same truck but going huron turbo t6 s475. That intercooler mount reminds me of my procharged fbody, I ripped it off on the first drive lol.

[@c63don77]

you're a beast man. I learn a lot from you

[@joelpittman2977]

Your videos are always informative, except I’d like them to inform me how to be a member🙃. Excellent as always

[@joelpittman2977]

Never mind! It’s there! Shoulda looked before I sooke

[@wesleyhryszczuk9442]

I also have the walbro 535 pump in my 2013 silverado 5.3, whipple 2.3, 3.70” pulley (currently) on e70 (with many more mods). But I installed and pulled out this pump configuration about 5 times trying different methods/modifications to the pump/bucket etc. and I finally have been running it now for a few months with a small rectangular hole in the bucket directly under the pump pick-up/sock. I was still having pressure issues before but this method has brought the most successful outcome to this point with maintaining pressure at high rpm’s. But I’ve also experienced erratic pressure spikes at idle and cruise that I have not been able to address. But it has not affected drivability as far as I can tell. Sounds/looks like buying a credit for the fpcm to modify a few settings could remedy that from the looks of this video. I may need a professional to do that for me tho at this point in my young tuning adventure lol I appreciate your videos man, keep pumping me out! I’m here for it👍🏼👍🏼

[@dalelockett2619]

Good stuff Matt! 👍👊

[@RadDadRado]

Awesome video, not much on this drivetrain setup. My 13 Silverado LTZ has the exact same drivetrain from the factory except NO DOD. Only VVT Long tubes headers are being installed this weekend. Looking forward to my retune.

[@Turbo6.2Silvy]

I got the same truck. I installed catless texas speed 1 7/8 headers, true dualed with an xpipe and corsa mufflers and tuned. World of difference. Def wakes the truck up

[@RadDadRado]

@@Turbo6.2Silvy can you make a short or video with how is sounds? I’m interested in the same setup. Agreed on the mods. Big difference adding headers.

[@Tignificent]

Do you find a lot of tuners are tuning na set ups with out checking or cleaning the maf sensor? Also ran into a truck where someone tuned over the fact that the fuel pump wasn’t holding prime. After replacing fuel pump the truck would be too rich and have excessive crank time turn into a hard start. Lots of sloppy tuning out there nice to see someone that’s doesn’t settle for nothing but the proper oem way

[@chanceshaw5001]

Let me fly you and a +1 out to Orlando and put you in a hotel for a few days for a mini vacation! Fix my tune while you’re out and spend some time doing whatever you want!😂 only half way joking lol Wish you were closer man. Keep up the vids. Awesome info

[@Matt_Sanford]

I tune down that way all the time. You can definitely hit up my homie @drtuneemall though. He is around Clearwater and he is more than capable of getting you dialed in.

[@chanceshaw5001]

@@Matt_Sanfordthought I responded but I don’t see it I messaged you on FB

[@juniorshallow7468]

Great video Matt!!! I have a 2019 gmc yukon denali 6.2L 10speed that I will be doing an d.o.d delete kit with btr stage 2 cam, am wondering if the transmission will need tuning as well

[@hops8184]

Correct me if I'm wrong but I think the 09-13 Sierra 6.2L had a L9H, which had VVT but didn't have AFM. 0:48

[@Matt_Sanford]

You actually may be right. I don’t do the mechanical work to them. I know there was some variations in the 6.2 truck/suv engines but I am just used to the majority of the trucks being factory equipped with DOD.

[@wisky3]

Did they do a hotwire on that 525 fuel pump it pulls alot of amps? Thats the reason i went with a 450 pump its more of a drop in, huron speed sells a nice billet twin pump drop in module.

[@Matt_Sanford]

This one was on stock wiring. They told me the FPCM had 10ga going to the pump but 🤷‍♂️

[@wisky3]

​@@Matt_Sanfordstock fuel pump fuse is a 20amp, I'm pretty sure those 525 walbros will pull 25amps.

[@GulfCoastTuningandCalibration]

Matt, for the Open Loop Tuning, what do you do with the maf table after you're done tuning on the ve table? Looking for more info on the Open Loop on the Gen 3 stuff!

[@Matt_Sanford]

The MAF curve is essentially complete after I tune the VE table. The only other thing necessary is I will take it out on the street and make sure all the data is lining up correctly.

[@GulfCoastTuningandCalibration]

@@Matt_Sanford and to compare the 2 in the scanner I believe the other videos says to use VE Air and DynAir? is that correct?

[@ryangrogan7247]

Which fuse do you pull on a 5.3 2011 canyon to make a pass it shuts me down from wheel speed I thought it was the pink abs 2 fuse it said stabilitrak traction control and Abs disabled across the screen just wanna be sure cuz there’s a green 40 amp as well that’s abs 1

[@g35tew]

I'll just have to bring my truck so you can work your magic...its awd i guess im out on the dyno but you could probably do i video on street tuning 🤔

[@anthoney5416]

Whats the difference in a car cam and a truck cam

[@nathangiudice]

Hey Matt how many credits from hp to tune that body style of truck?? Thank you

[@CLW83]

Would it be better to change to a return style fuel system?

[@Matt_Sanford]

Absolutely. I would always prefer return style in a forced induction application. Especially in a vehicle from this era.

[@CLW83]

Sweet that is what I planned to do 👌 Also be a good instructional video.

[@hotrod76.]

I wld have thought a 6.2 with a pro charger wld have made 650 plus.

[@Go4BrokeOffroad]

I know you said 2 bar a few times. Those offsets and kpa numbers look like a 3bar.

[@Matt_Sanford]

2 bar is what the operating system is called by HPtuners. You can scale the Map sensor to pretty much whatever you want though. But yes it’s a 2.5 Bar CTS-V sensor.

[@Go4BrokeOffroad]

@@Matt_Sanford ahhh gotcha. New to HP tuners for sure.

[@nate-xn5gt]

hey matt, i sent you an email regarding a tune, i would love to have you do it, the email address that i sent it from starts with 700, its for an 01 truck. thanks!
