I have an entire turbo kit with your name on it! its a 67mm with obx tubular stainless manifold and wastegate. Ill let it go waay cheap. Its been on my car for 4 quick starts. Never driven with it.
for something like that, from what ive read, you can use an safc or a apexi power fc for tuning purposes. Also the 93+ computers are more tunable than the 91s.
