Ok my car is way too rich so my turbo only spools until 4500 rpm then blows black smoke out my wastegate. i have an apexi safc II but don't know how to tune it and nobody around me can either. if anybody could help me that would be great thank you.

ok so, when your just driving around, not in boost, youll want to tune the lo map till your a/f gauge bounces around 14.7-15:1, and tune the high map for when your in boost so that the a/f is right about 11.5:1 . if your anything richer than 11:1 under boost, your wasting gas, and leaving alot of power on the table.
how much boost are you running, and do you have a water injection kit? if you want the setup to last, i would strongly suggest not running more than 14-15psi, and get a water injection kit on there with a 3 or 5gph nozzle asap. with the WI, and a decent tune, the car should pull hard, and will last a good long time, provided you take care of it. -------------------- Former Team 5SFTE pro member ;)

I echo this..I was going to say the same thing..be careful though, running too lean with a turbo will end up overheating your turbo..here is a nice little chart for you, ignore the right two columns. I would try to find out why it started running rich first though.
