Thanks. Fuel pump made a huge difference considering the 1 it replaced didnt pump fuel. Having said all that are there any tt ecu\'s i could that would make a difference? I\'m pretty sure its an R6 in it now, blue sticker anyway. Im guessing not due to compression differences. Theres no problem with how the cars running or anything, its smooth, cheap on gas, beats b4\'s and keeps up with/sometimes passes sti wrxs, so im not really after more performance or anything, more a learning thing for myself, see what parts i can frankenstein together to get what results. One thing i would like to fix is the VoD that i\'ve nearly got gone, only drops 4-5psi when it opens up i/c valve now. I know really the only way is ST conversion but thats boring.
