should the stock fuel injectors and pump be enough to carry my greddy td04h-15g at 7psi??? the car seems to be getting lean at the top of 2nd, 3rd & 4th. i have a 95 del sol with a d15b7. any help would be greatly appreciated!!!

do you have any kind of a device that you can rely on to tell you that the car is leaning out? Like a wideband O2 or a egt gauge?
What is your total fuel setup?

I have a 94 del sol 's' and my pump wouldnt keep up, but have different motor, d15b jdm vtec. I also have different injectors 450cc. It almost cost me my motor, that sticking fuel pump. Be careful, I had a wideband and fixed it before it screwed everything up. Walbro 255l hp, is a good pump and they might still have the deal on it for H-T members, if you contact the lighting motor sports. They run a banner.

i wouldn't really go past 5psi on stock injectors with a fmu. your fuel pressure will be pretty high(or will try to be)....

thanks for the help! no i only got the very unreliable autometer a/f gauge. but it does feel like it loses power at the top of every gear, and the gauge goes red. only tried it one time, now i don't get past 4-5 psi.
