so we are tuning a stock ecu s5 t2 with an fcon. it has all the emissions removed.
we put it on the wideband and you can see it go lean over 5000rpms, ok so we keep turning up the fcon and that just makes it bog harder below 4k but it really didnt change over 5k rpms.
we were thinking fuel pump until paul suggested the fuel pressure solenoid.
check the codes, we get #25, pressure regulator control (fuel pressure solenoid), i plug solenoid into connector
BAM!
10.9:1 afr all the way up to redline, problem fixed
this could easily pop your motor.....

I thought you said you removed emissions? Is this not in the rats nest?
