    Running mods on stock ECU tune

    Currently my P-X is topping out at 8500 RPM with the parts listed in my sig, and running a V-Tech tune. If I tune it back to stock for a day, and adjust the fuel pressure to 58 will it harm the ski? Obviously I'd be hitting whatever the stock limiter is, but is this bad? How does the stock tune actually limit?

    Don't you have an afr gauge to verify?

    Mine runs perfect afrs on the stock tune, wot is 12.3, part throttle is also good
