I installed an intake, header, and injen axle back. Now my check engine light is on. If i buy a GFchip for my scion will the light get tooken off? and will it improve my performance??

 

Your check engine light came on was cause you have an aftermarket header. You will need an anti-fouler so that it can go away or put back your stock header

 

Where can i get an anti fouler?

 

you can either get it from here http://www.racingsolution.com/scion/...ti-fouler.html or some other site. or you can make one ursleft for 5 bucks. http://clubsciontc.com/forums/diy-in...scratch-35021/

 

Alright man thanks! And that chip you think its worth it?

 

All of the "chips" for the tc are a gimmick. The only thing that works is a piggyback, or standalone ECU, PERIOD. Going with a piggyback/standalone + tune for N/A bolt-ons is rarely worth it. The gains are going to be in the <10whp range and the cost will be close to $800-1000 after you get the pickyback, harness, install, and tune.

 

Alright thanks
