that is the plan. i need more fuel cause im already maxing these injectors +40 on high throttle and air fuel ratio is 13.5 at 6000. (shift point is 6400) only 1 person has hit 200whp from what i know and thats on 15 psi and a 40 shot. id really like to build the engine but i have to want since no moneys. thanks for the replys guys!

I just used a aftermarket walbro fuel pump for my setup (255). Before we tuned my setup on the dyno it wasnt making to much power, maybe 140? The tune is what reallly got me up there though we tuned rich. Running such small power (these t25 turbos really are crap lol) the boost doesnt affect the motor like you would think. I pushed 15psi on stock internals Daily driven (and seriously beaten) for almost a year before the thermostat got stuck and my temp gauge didnt work leading me to a broken ringland on a hard pull =-( Dont be afraid to raise the boost when your ready, these turbos are cheese.

so is my 13c comparable to a t25? cause it sure as hell does not pull like one. all of my power(and it may be due to the automatic) is above 3500 rpm. i have a friend with a lot nicer manifold and a dsm t25. it also pulled at lower rpms. im talking 8 psi at 2200 so if that is the case then i just need to put my booster pump in. grrrr its so fustrating. so let me ask this. most people say you want to tune in 3 gear and my a/r on the wide band will be steady at 13.5 and sometimes hit 14.3. should i add more fuel? reason why i ask is my high setting is at +40 already. i just do not want to over max my injectors.
