Please review my tune 2010 Silverado 6.2 with 76mm Turbo
Hey guys,
New member here, overwhelmed with everything I have to learn, but excited none the less at all the possibilities once I do.
Please review the tune on my Silverado; its a stock 6.2, 6l80 truck. Ford 60# injectors which I am told are closer to 72# on GM's 3bar fuel system? 76mm Turbo, 91 octane gas with Meth injection stock 1 bar map sensor.
I am happy with it overall, made 600WHP on 12.5 PSI. But I have lost considerable gas mileage since the turbo went on, 15.5 MPG to 9.9 even when I stayed out of boost and was mainly highway driving for 2 days. I am hoping that there has got to be things that can be fine tuned to help this.
Any and all help and advice is greatly, greatly appreciated.
I am getting some false KR from exhaust pipe touching frame (soon to be fixed), but every once in a while I think I am seeing the real thing?
Are you able to see/log your cruise afrs? I'm on my phone, so I cannot see your attached files.. but I hope you have at least a log in there showing the issues you've explained.
