--There is no tuning for the IS-F, or any Toyota, because the ECU has never been, and probably will not be, cracked.
--Look at PPE headers, they are probably the best.
--No forced induction (several companies have tried and failed) due to no tuning for the ECU.
With headers (PPE or Sikky) and a full exhaust (Joe Z or Borla) most people are getting about 385-395whp. Keep the stock intake because most just make noise or lose power for the car.
