My GM TBI setup isn't providing enough top end power for me. I only drive trails - maybe 200 miles/year so I am not concerned about mileage or emissions. I am looking for the max power I can get from a stock 2F engine. I have a PROM burner and eraser so I just need the file to burn - I MAY be able to tune it from there, but I want to start as close as possible for what I want to do. Anyone have a file that they can share legally? TIA.
