Hello everyone. I am almost at a loss on this one. Small background info, I own over 200 credits and have tuned a lot of prior Gen V stuff and have done some smaller Gen V jobs prior to this one just a little insight on my experience level. I have been asked to tune this 2015 C7 stingray I think, definitely not a Z06. I had no part in putting the parts on the car or any of the decision making on part choices. The cam is a Texas speed 25-TSPLT1VVT-3-32 (phaser lockout), yes I know, stock LT1 HPFP, LT4 Injectors (19420801), heads of some sort from Texas speed, and an MSD Atomic Airforce intake manifold with a Katech 103mm TB and some other aftermarket intake. I have the car driving pretty well aside from about 1200 rpm to around 2000 rpm and above .3g's of cylinder airmass it goes lean and falls on its face and fuel trims work their way up over 28%. I do in this file have SOI flat out a 280 which i know isnt great, just trying to rule that out which I had no noticeable change. I had scaled for the 32% fuel lobe and entered LT4 injector data from a 2015 Z06. Only changes I had made for the HPFP was the scaling for the fuel lobe. I have not finished the Virtual Torque stuff yet so some of that is off still, VVE and MAF seem to be very close which I did tune. Attached is a log of the current file that is attached as well. Im all open ears and appreciate any input.
