I did a HPDE at Rivers Edge road course yesterday in my S4, it was the first I'd taken it on the track, car was a lot of fun considering it's weight and weak brakes. The issue I had was coming out of right hand corners as soon as I got on the gas the car would completely cut out. Like hitting a hard limiter. Weird thing is it was fine every time on left hand corners. I thought it might be fuel starvation because it seemed to get worse throughout the day, but I filled my tank before my last session and it kept happening. I didn't get a CEL or EPL light, so I'm kind of dumbfounded as of now. I will scan it for codes tomorrow and see what comes up. I'm APR stage2 93 octane map running chevron 94 octane gas with 0 ethanol. Any ideas what's going on?
