Hello,
I recently put on long tube headers on my 07 FJ, along with a straight y-pipe and JBL exhaust. All my lights came on on my dash, and I'm running extremely rich. I'm getting 9 to 13 miles per gallon. I've called around to different performance shops but no one will tune an FJ. I live in Michigan and I have called around to some shops in the surrounding states, and have had no luck with anything. Does anyone know if there are shops that can tune it, or if there is a computer I could buy online and do it myself? I had no problem with the set up, cold air intake included, but when I got rid of that cats and put the long tube headers on all the lights came on. I'm looking for any solutions.
