I have a 5 speed 2010 scion tc ...i dont know what else to put in it...i have dc sport headers, k&n short ram intake, and spec-d catback exhaust... However i feel like my tc is laggin in power...any tips of what to do to gain hp not loose it?

 

There's not really any other bolt ons available. Your only choice would be to go F/I

Sorry, you could get it tuned but I don't know if it would be worth it money wise.

TURBO!

 

Strip out your interior and get lighter wheels

 

If you wanna stick to bolt ons look at some lightweight pulleys and a tune
