    ? about max RPM on 130 and 155

    I have a 2015 GTI 155 and rode it the other day and max RPM's were 7400 and my son rode a 2017 GTI 130 and max RPM was 7080. my 2015 is stock as far as i know, i bought it used with 27 hours and bought the 2017 brand new 2 years ago and just installed a new Solas 10/18 impeller and wear ring. the 130 actually sped up by 2 MPH and now tops at 54 mph and my 155 tops at 55 but my relive app actually said top speed was 57 this ride but that was in a fast current going downstream and i was watching RPM at the time on gauge so never saw top speed on gauge.

    my question is does anyone know the factory top rev limit on each? is it safe to do a racelab tune or other tune to increase max RPM on both engines? without reducing the reliability? I wonder if i am hitting rev limit or if that is all the power the machines actually have?

    now that both machines are so close to performance due to new impeller i am tempted to buy the same for my 155 and see if i can gain a little on that one also. I can just barely catch and pass the 130 now.

    video of us riding.

    Here is a good thread I am in with my wife's 15 155 se gti. With speeds and rpms.

    New speeds are at 62 at 7600ish i didn't record it this time. I have the max speed and rpm on the dash but forgot to take a photo. I WILL update it next time out for proof. Nothing is believed unless there is proof these days.. lol
