I own a 03 S2000 with a comptech S/c, invidia testpipe, and invidia exhaust.
I have owned the car since late January and had no real problems. But on Friday i started it up n drove down the street and the CEL came on. I took it to get checked and the code i got was P0170 meaning i am running to lean. My engine check light went off before i took it to the dealership but i have not drivin it since i have found out wat was wrong. I know that getting a ems n bigger injectors n everything is what i should do n i what i want to do but i can not afford that as of right now. is there any information or help u can give

 

running 6-7psi should be fine with an fmu, but u never know when it really leans out.
