Installed a Catless 3"DP + Ran stage 2 MAP from cobb at first and car was running fine for a while. boosting max at 14psi & suddenly it started only hitting aroun 11psi max. So i decided to run stage 2 HWG map from cobb.
Datalogged with a stage 2 91otcn HWG Map from cobb. just wanted to share & see if i could get some answers since im fairly new to tuning and datalogging.
