i got a 89mk3 turbo running way to rich. no codes, cant drive over 20mph and wont boost. there alot of black smoke coming out of the tail pipe. i just replace a head gasket and it not running right. i just install 1.2mm hks head gasket and arp studs. torque it down 75foot pound. i check the tps, mass air and timing, and i dont think there any vacumm leak. Everything seem to be with in spec...i dont know if the ECU is mess up. if someone can help me... please help.
