I bought the car with a t-25 turbo set-up with stock injectors, and a SFMU, what is the biggest size injector I can run with what ratio disk, without using a SAFC. i think this might be why the turbo isn't catching and is real slow off the draw. if you have other suggestions let me know please thanks.

sounds like a blown turbo to me ;)

Do you have any boost leaks? Also you might want to check to see if the wastegate is closed all the way.
BTW make sure you dont use the safc to correct fuel that much. It advances the timing and boom! Use it for small corrections and use the SFMU to the fullest.

turbo8u> shut your SUCK

well i don't think it's blown for the fact that it still kicks in but not for awhile. i guess it could be if that is what happens. like even when i pass and stuff it doesn't kick in. it's like it takes a long time so then there really is no kick you know. only sometimes and some speeds. its hard to explain

can we have a picture of your setup ?

and just for one test run, disconnect the rubber hose that goes to the wastegate actuator if you see no difference the wastegate is stuck open this happens once in a while

are you a 420a or 4g63? how much boost are you running? my T25 kicks in at full boost at like 2000-2500rpms. and i'm running 15-16 psi

Yea mine also gets going so fast that it is like having a supercharger. If you have a 4G63 then you probly have a blown turbo, (new berings and such are pretty cheap), if you have the 420A version with a custom turbo kit, then you need to mod your wastegate actuator different. That is what is holding you back.

he's turboed 420a, similar to rxr eclipse above me
