Recently had my car "Pro Tuned", it's running same times as it was stock with all the mods and tune (1 7/8 headers Speed engineering headers & Xpipe, Rotofab dry intake, Flexfuel sensor) No TCM tune
having some doubt about what this tuner has actually adjusted, AFR when cruising will flip flop from 13.5 to 15.0 every few seconds while on E85 (93 AFR stays 14.5-14.7) (WOT AFR 11.2-11.8 for both 93 and E85)
If someone can help aid what to fix in the maps, or recommend a tuner that can help remotely.
attached tune and logs from tuner.
