Just finished my first swap b18b to B18c .? I’m running a p72A04 ecu. The local tuner shop said I need a p28 to tune it. Basically stock gsr, skunk intake, dc header and exhaust. Msd coil /dizzy /wires. Should I just run what I have? Or do p28/ s300 and jumper? Thank you very much for your time and help.
