Fuel pump upgrade question...
I think I asked that before...I'm pretty sure that is a no-no with base maps
I've chatted with WORKS before on the phone about that issue and they said on the evo 9 the need to upgrade the FP wasn't necessary until larger turbo or cams....but whatever...as soon as I get Protuned we're gonna slap on a walbro just to be safe.

Not really sure....maybe cobb can answer that...your best bet is to call them as they don't surf in here too often
