i have a gsr with inline pro adjustable cam gears, does anyone know what i can advance or retard the cam timing without tuning and run with a stock obd1 gsr ecu
right now the cars only mods are blox intake mani, type r header, type r throttle body...thanks for any advice

 

No point. Don't mess with them unles you are tuning on the dyno. I'd advance ignition timing before cam timing anyways.
