what should my base fuel pressure be around on the follwing setup

d16y7
greddy 15g intercooled kit @3psi (stupid pressure loss, need an mbc)
fmu 12:1/missing link

the car seems boggy down low and will barely move until i give about 50% throttle and get up to about 3k rpms, also on the highway in 5th at 60 miles perhour it wont stay at 60 unless i am giving at least 40-50% throttle according to my safc.

what should the base fuel pressure be? stock fuel pressure?
i am installing a bm fuel gauge soon so i just wanna make sure of whats going on, it seems the fuel psi may be too high which is causing a bog down low until the boosts hits in which the fmu disc is activated. Would a fpr help too?

 

ttt

 

anyone

 

grrr

 

well if you dont have a FPR it doesnt matter what base pressure is becuase your already at it, unless there is somethnig im missing.

 

hrmm, any idea why it would be so dodgy down low and only pick up at around 3k at 50% throttle? i dont have a secondary o2 in (in engine bay "hiding" from ecu), think that has something to do with it?

 

shitty tune maybe . thorw it on a wideband and check the tune.

2nd o2 does absoltely nothing .

 

with 3 psi, anything will be boggy ... crank that bitch up!
stock injectors? Check your plugs too

 

plugs are fine, they are bcpr7es gapped at .030, i am buying a mbc today and am gonna turn it up to about 6 psi

 

you dont need that cold of a plug and that tight of a gap, that could be part of your reason. an MBC wont help. if your only making 3psi , theres a prob

 

what kinda plugs and gap do you suggest on my single cam?

 

you can get away with stock on that little thing. 7's are like 2-3 heat ranges on that motor.

 

ok cool, what are the stock plug numberS? can i just run the stock gap?

 

anyone else?
