Hey whats up i've still not had time to get on here too much, finishing up finals this week. I think im going to go with those stillens man. Just had a quick question wondering if you might know. I know they hook your vehicle up to a comp here in collin county. I was told by someone the other day that, even though the elluminators keep your check engine light off, the mechanic can still read on your ecu that your o2 sensor is not functioning correctly. Do you know if this is true? Id love to have headers on the truck but def cant afford to put them on and fail inspection right now. Gfs got a babe on the way and she takes alot of my mulah.haha. Ive got an 04 too. Its a crew cab LE with 6in lift and 3in body lift. The body lift is retarded Im taking that off, but it was on when i bought it. Anyways man let me know if you know anything about the ecu.
