Yellow Chevy you make it to my town lol
if i ever decided to change again im gonna try Korys tunes but i dont plan on changing anytime soon as ive had no issues with Bobo's tunes and the truck deff runs hard. But for me its all about whos tuning my truck on the spot will never do the email back and forth stuff seens lots of issues with that kind of stuff and dont feel like wasting a whole day going back and forth with someone when a in person tune can take a few hours, just my .02 regardless man give a few people a call and whoever you feel comfortable with in the end
I tried Steve Schmitzers tunes, driveability and fuel mileage were very good but he couldnt get my truck to run like it should. He tried 4 or 5 revisions and pretty much gave up, and he aint cheap. I'm running Diesel Addiction tunes now and the first race tune he sent me was at least 50-75 hp stronger than the last I got from Steve. I guess it depends what your looking for.They are all good at what they do. Each one will most likely make you more than happy with there stuff. Some trucks just take alot of fine tuning and time to get done right. Which shouldn't be a problem for them, its "custom" tuning. Pick any of the guys mentioned and you can't go wrong.
From what I have read recently, like above , steve schmidt has pretty damn good customer care. Personnally never tried his stuff but thats always a plus. Trentnell was always good to me asking about how things were going and if something needed changes aswell. Haven't seen him online lately though, probably pretty busy right now.
