Hi all

Wondering if anyone has experience in modifying the tune written into the factory GM FSCM. I’m referring to an E67 driving a factory LSA powered car, seeing if I can get any more juice from the factory pump.

At present I have a pressure drop to 355kpa at around 6700rpm at approximately 540rwhp.

Thanks!
