Most likely wrong place to post but I just got tuned like three days ago everything was all dandy until tonight...I go full throttle and a/fs go from around 11.4 (give or take alittle richer) right to 12.4 right around i'd say 5k rpms it may even happen sooner. Right when I saw that I let off tried again same thing and let right off...any idea besides fuel pump and all that nonsense. My a/f are not lean normal driving they are fine. Are there like any possible glitches in the ecu because it was a flash? Anyone else have this problem on a fresh tune

 

Did you change or do anything different or just driving it? Fill up at a different gas station?

 

Take it back to your tuner.

 

take it back, and have your tuner make sure the tune loaded 100%

 

didnt change gas or anything until i saw it do it so i put some more patroleum in and same thing im gonna call today and see what he says
