Just finished 2 boats each with 502 EFI. Installed custom cam grind and reflashed the ECU.

1) 1993 29 Fountain - 502 MPI, VST
2) 1994 272 Baja Islander 502 MPI, VST

What is your ride?
How is it currently configured?
What year engine package are you running?

Assuming you are still using the VST FI system there a few things you can do to wake it up.

1) change exhaust
2) change the cam
3) flash the ecu

If interested I have a package that works great on this engine. You will have to have your engine shop re-work the heads for spring pressure, Or depending on your location I can do the complete job.
