okay so i just bought a 1988 mk3, and it has a bigger turbo not to big and not sure on the size, guy i bought it from didn't kno, it also came with 750 injectors, when i brought it home the car wouldn't rev over 3500rpm's it would start to break up, so never messed with a safc. did a little research end up changing throttle position from 39 50 to 69 70 and messed with fuel correction on hi throttle only, and left the lo throttle at 0 for everything. now it goes up about 5600rpms without breaking up, but then does it again, is there any way to get this tuned with out a WB or do i have to get a WB to get this thing perfected.
