ps wtf i did not ask about hp just fuel psi
it might make 275 hp if i get it right.

any help please?

 

A T3/T4 with a 67HO wheel and a stg5 exhaust could require 3-5x the fuel that a T3/T4 with a s-trim wheel and .42ar T3 housing w/stg1 exhaust.

If you bothered to read how a turbo works, as well as how fuel injection works, you don't just raise the fuel pressure. The untunable/unpredictable nature of the FMU also means you'll be missing out on a lot of HP even if you get it right.


BTW can you define "lazes" please? I can't find it in any online dictionary. Does it mean SMOKES or BACKFIRES or BAKES COOKIES, what?

 

whats the conversion factor from hp to fuel pressure? cause thats what he needs to know so he can go fastor!!!1 tuning with fuel pressure ftw!!

ok ok, seriously though, OP please read through the archived threads, lots of great info, the majority of people here do not like to use FMU's and will not advise you use one. Getting in contact with a local tuner is a good start.
