    Performance 2012 rxp-x After 8350 Tune?

    I just recently got the 8350 48lb injector tune and loaded it into my 2012 rxp-x.

    I have 4 inch fizzle, 15/20R prop and thats all. I already turned 72mph at 8040 rpm without the tune.

    What performance increase should i expect with the 8350 tune from vtech?

    VERY CURIOUS since it'll be till tomorrow afternoon till i test my ski.


    Oh also! i disconnected my gps delimiter from riva with the understanding that the vtech took this limiter off right??

    I will guess 75.2.
    Yes, the Vtech removes that limiter

    I'm going to say little to no gain without depitching the prop.

    That would depend on where the rpm hits before it drops back to 8040 right?

    True, I always forget 8040 is soft limiter on these.
