V8 EJ207 Running Rich
Background info on the car:
172k miles on chassis and drivetrain 70k ish on V8 EJ207 W/ AVCS Full exhaust Stock twin scroll turbo Grimmspeed 3 port 1000cc injector dynamics E85 Intake Turbo inlet Tuned by Eric Minehart Now to the problem The car idles and cruises perfect at 14.7 on the AEM wideband. As soon as you start to go WOT the car slightly bogs and the wideband reads 10.0 and tapers slightly up to 10.8 in the higher rpms. I’ve replaced the front o2 sensor, IACV, cleaned MAF, replaced spark plugs, and thoroughly searched for vacuum leaks. Unfortunately I can’t log anything right now as my ECU isn’t connecting to RomRaider.

Check for boost leaks. Had a very similar situation and it ended up being a slightly torn inter cooler y-pipe.
