    GTR215 V-Tech questions

    Hey everyone, New to the forums but been lurking for awhile. Getting ready to pull the trigger on a 4" intake and looking into the V-Tech 8375 tune. Those of you that have ran this tune, is there a noticeable difference over stock? Any issues with overheating or failures? Thanks in advance for any input!

    The biggest advantage to a tune is that you are no longer restricted to the 67MPH ECU restriction.

    there are many 8375 maps
    some are close to stock
    others have big changes
    and when you upgrade you can change maps
    or modify your map yourself
    by raising the rpm limit adding more fuel and changing timing

    What tune would you suggest for a stock ski with an intake, looking for something that'll give it a bit extra but don't want to run it on the edge and blow it up..

    Have that few people messed around with the GTR yet? I figured alot of people would be modding these due to weight and pricepoint!

    You will need to change or repitch prop for best gains of tunes ...

    So would I be wasting money and effort doing a tune/intake without a prop? Not really looking to dig too deep into the ski, just want a bit more than stock has to offer!

    ...after the ECU limiters are gone, the limitation is the hull. the hull seems to hit a wall around 74ish.

    a 4" air, ECU flash and an impeller will probably get you pretty close to that w/o spending alot of money for 1 or 2 more mph.

    My GTR will probably get a 4" air, and maybe a re-flashed ECU.

    But after much consideration, I'm pretty sure I see a P-X in my future to get my mod on...

    Well my friend if you do the tune you would probably be the SECOND one to do it, Since I am the first!!! Huge difference! Pulls hard, acceleration is sick, top speed is increased 3-4 mph..No issues with overheating or anything. I believe my ski ran 69/70with the tune. I also added a modded rideplate (to get the nose up) gained another 1.5 to 2 mph from that. Never touched the prop yet, have a 4" air intake as well was my first mod. Heres a vid!

    Yeah I've heard that the hull hits a wall around 74/75, I've thought about selling for a different ski, but I just love the weight and fun factor of the GTR! That and you don't see 40 of em on the lake like the other skis lol.

    Bam!! That's what I like to see, solid evidence lol. What specific tune did you go with and t-stat? Also, any more info on the ride plate (price, difficulty of install, did it change ride at all)? Sorry for all the Q's but I gotta pick your brain a bit haha.
