if your check engine light is on, you must've installed the blue box wrong.

the greddy kit runs really rich and i even have a flat spot in mine around 6k where it just boggs down. but next week it will be tuned with uberdata and rc 550's and the shop tuning it said i will have about 275 or so WHP.

shmoo, if you are running the e-manage, you will need to get a FPR to raise the fuel pressure, incase you didn't already know.
