How manage to get more horsepower on 3s-gte ? Options

[Iceman22]

Hello. I have 3s-gte with a turbo boost controller, turbo timer, fuel cut defender and a blow off valve. On 1.1bar on the boost controller i have around 300hp, and when I don't use it then it has 260hp.
This is really enough power, but why not try some more if it is possible? What parts could do to manage for example 400hp? Is it possible? My friends told me a boost fuel pump, camshaft and chip would help much, is that right?

You have plenty of fuel left for 400bhp with the stock 540cc injectors and Walboro 255 or Supra TT pump. I made 330whp at 21psi (1.44bar) which would be around 380bhp figuring 15% drivetrain loss on the FWD LSD transmission, all still on the factory CT20B.
At 24psi (1.65 bar) I made 342whp, which would be right around 400BHP...and my AFRS were still in the mid 10's.
If you are going to turn the boost up past 18psi, I would recommend getting water injection as an added safety precaution

did you raise the fuel pressure, my stock 540cc's are at their max at 17-18psi (100% duty cycle to hold 10,5 AFR)

No, I did not raise my fuel pressure. This is a 100% stock GEN3 fuel system, supplied via a Walboro 255 pump. What turbo, ECU, Generation 3sgte, mods, etc are you running?
