How much boost can i run?

[clipse-T]

My mod list.. Evo3 turbo, full 3" exhaust, K&N FIPK w/ dejon tool pipe, 550s injectors, 255 pump, FMIC, type-s bov, SAFC, boost and egt gauge. Currenly am running 18psi with 92 octane..whats the max boost i can run with this set up? I wondering if i get 650s injectors would i be able to boost more than 550s? Any help is appreciated.

Do you have an AFPR? You need one with the 255 in there. Any more boost than what your running, and it would be advisable to stud the head. Get a wideband gauge, such as the AEM UEGO, and something to datalog to see injector duty cycle. Only then you will know how much fuel you can have with how much boost.

yes i have an AFPR..sorry for leaving that out. The car was tuned with a wideband and the SAFC. I got up to 20 psi with the 550s, is that my max?

honestly get someone around you who knows whats going on...the egt gauge will tell you if its running right or not.
