Someone out there has to be able to help me... I installed an sts turbo on my 2011 5.3 silverado. The problem is the tune sts gave me is running way rich.. to get an 11.3 afr I have to take 40% fuel out of the system. So sts sent me a new tune that was supposed to be 40% leaner. This time I had to take out 35% fuel to get to an 11.3 afr at wide open throttle. We have been working on getting this tune dialed in for two months. It seems I can get it close on my diablo intune but sts cant even come close. Are there any machanical issues my truck could have? Does anyone know marc from sts as a tuner? Rick sent me a tune for my last truck and it was spot on. Any input would be great

Those are some mighty big amounts of fuel to be off - sounds like someone isn't doing what you are telling them. Hard to say for sure without seeing the tune and what they are changing...
