I'm trying to help out a friend who was left with a not so good tune from a "tuner" I can upload this guys tune when I get back to my laptop. He said the truck was wanting to die on deceleration. And would buck really bad.
Anyways. I went and downloaded a stock 2010 5.3 tune and started clean. Disabled vvt and dod. Bumped some of the idle settings up, it runs without stalling, it smells and sounds way better. But it just lacks low end power (under 3500)
Would love to really learn how fo tune this truck, but would be happy if I can get someone to have a look at what I'm working with, maybe tell me what adjustments I can make.
2010 silverado 5.3. Cold air intake. Aftermarket maf, headers, no cats, exhaust system. Pretty basic. Stock truck intake. The engine block was out of a 2008 but all the 2010 stuff was used.
Made a bone head mistake and had the stock internet downloaded tune on my HP tuners program and went and used 2 credits unlocking the wrong vehicle.... whoops.
