my 03 sti is running 348 bhp with ppp and a remap by jgm what would be the best way to go to up the power?

 

Turbo,injectors and another map

 

Oh and a de cat if you havent already

 

Buy a JDM and upgrade that.

 

Simple question stupid answer

 

fooking fone

 

Best to speak to JGM if you used him as I assume he will be doing your next map, he knows his onions

 

It's not a PPP car anymore since you have had it remapped, but as said you can do one of two things, bigger turbo (more lag), injectors, exhaust (as the 2.5 will be a little more restictive than a 3 inch), panel filter, or buy the JDM twin scroll and upgrade that with one of litchfields turbo's, it will be a pleasant shock having power all the way through the rev range instead of above 4k
