sup guys, just finished up my 5sfte project. im in the middle of tuning right now and i stumbled on a small issue. im sure its something minor. but whats happening is that my turbo kicks in at 4k rpm and its only boosting around 3psi max lol
its feels great though. since i work all day and only rest on weekends its hard for me to diagnose at the time because by the time i get out of work its dark... anyway im thinking it might be that i have too much free play on the wastegate actuator arm or a leak somewhere. do you guys know what else it might be? would back pressure affect it? i ask because my down pipe is a 2.5" and drops down to a 2" to my stock exhaust this is my first turbo project and its been a blast..... so help me guys! lol specs on car: 94 gt 2.2 rebuilt ported and polished 460cc injectors Safc2 t3t4 external wastegate turbo 7psi spring fairly large intercooler with 2.5 piping |

P.S. As long as your turbo is efficient where you want to run it, you have good enough fuel system and correct timing, you won't have any detonation.
