This is on my car, a 2009 Pontiac G8 6.0. Some background info in case it is helpful:
DOD Delete
Heads shaved .030
Cam Specs: 219/223 .625/.625 with 112 lsa
Stock manifolds
I do not have a wideband installed yet. I have the car running fairly well from what I have learned on here but I have a KR issue still. I noticed it on 87 octane and decided to run 91 premium no ethanol today as a test and still notice KR. It took a couple of drives for the STFTs to get back towards normal and then I took a couple of logs. I never went over 3000rpm during the logs. Also the temp outside was about 70F.
They are posted with the tune. Any help is greatly appreciated.
Thanks!
