    87 gets it moving sooner. 85 gets it moving faster.

    Dude, just keep whatever your setup is now. Your prop should be around a 14/20 with a 4" air intake. It's still a gpr, and you were the master of that 120066V. Start there and run with it!!

    Mark or anyone else with this knowledge and experience, can you update this thread? I'm most interested in stage 3 minus the ECU or more stage 2+ on the stock ECU (same thing really)..
