I am about to make the switch from an sts-v that I had helped develop many of the performance parts for and am curious what is available for the is-f as far as this goes. what Im looking for information on,

-tuning= very Important when you start modding any car and to really get all the performance out of it I would like to know what Is available for this.
-headers= I have seen a few options available and am slightly curious as to how ppl are running them without tuning to be honest, any insight on this would be great as well.
-FORCED INDUCTION= I know I will miss my supercharger, so that will be a plan for after the car is paid off. curious if anyone else is running forced induction on theirs and what gains are to be had.

thanks yall!!

--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.
