So this is my first Toyota car that i have done work on, My question is, when boosting a 2005 Scion Tc how are you guys going about tuning the cars. On low boost cars (under 10lbs) are you able to piggy back the ECU? Also on higher boost what programs are you using? No hondata that works on the Scion or carburetor hahah :lol:. thanks for all the help guys/girls.
