Hey guys I need some help with my 11 evo x.
I got the car a while back with some mods already on it and I noticed right away it was running lean on e85 at wot, 13 afrs.
I took it right away to a very reputable evo shop/tuner. Got it retuned on both e85 and 91, as soon as I got it back it ran...
My fuel setup:
Aeromotive 340lph pump, 10ga wiring - directly to the battery. No dual-stage voltage.
Boomba Fuel Rail
~38psi base pressure
A week ago, everything was kosher with my fuel setup.
Then just the other day, I started leaning out big time under high rpm WOT...
