I honestly thought a stock 6.2 would beat a stock duramax but I was wrong

 

No kidding, I was hoping after headers/exhaust/tune I would be able to take most 3/4 ton diesels. Looks like I was wrong, but hopefully a cam and 4.10s could up the odds a bit more.

 

some good vids definitely. I can't believe how much difference there is with the tuned 6.2 and the stock one. who tuned it?

 

Looks like the tuned 6.2 will hold its own.

Its nice to see all the stock vs stock.

But if that Dmax ever gets rid of his DPF and gets a tune,,, bye bye

 

My buddy in Jasper with hp tuners tuned it! Mine was the stock one against the ford and all the vids except the tuned 6.2 and duramax! Mine will outrun the silver tuned one now till bout 85 or 90! His is tuned for 93 and I'm on 87 tune!

 

Bring em to us 400$ a pop! Guarranteed to perform and get great gas milage! We spent prolly 7 days R&D on the 6l80 and it is badd when set up correctly! My silver truck in the vids has 75000 miles on it in one year and is an awesome ride! Yes the denali wheels hurt its performance a little but needed the look. We can tune em in one eavning. Like I said 400$.

 

thats awesome man, but you should really fed that 6.2 93 octane.

 

I would if gas wasn't $4 a gallon! Ha

 

We are fixn to work on an E85 tune so thatll prolly take a bit! Just FYI there is an app on the iphone called e85 fuelfinder that gives numbers and directions to stations that carry it. Just saying

 

I've thought about doing an E85 tune since I run it exclusively in town because I live 3 miles north of one station (which is on the way to work) and 6 miles south of another that carry E85. I know GM lists separate dyno sheets for the 5.3 flex fuel motors showing that they make more power on E85. DOes the factory ECM have different tables to run off when it detects a certain % of ethanol? I know an E85 tune would make excellent power, but my concern is if I go on a road trip and have to run 93. I don't know if it would still operate like the factory tune where it would just start running on another table with the different fuel..........
