HELP sputtering prob

[nskyle]

hey im a noob please help. i just picked up my RB20DET powered s13 2 days ago pushing 10psi of boost. on the test drive it ran fine. now it sputters after its warm. the air/fuel gauge reads lean but my fuel pressure regulator reads 43 or so. that's right where it should be right? the mods are chip. 3'' exhaust all the way back. hks air filter. real basic stuff. someone help me before i blow it up. thanks

im thinking its getting to much air that's why its running lean. maybe a clogged fuel injector idk

Did you upgrade your fuel pump. My car wouldn't even start until I changed it out to a z32 fuel pump. Also check to see if your throttle cable is touching the hood.
