    Three free V-Tech tunes to give away

    Hi guys, as many of you already know, we are now offering ECU programming for the FX SHO and FZ series skis. The VXR tune is not quite ready, but hold tight as it won't be much longer

    I am looking for three ECU's and your ski must meet the following criteria:
    We are looking for members here with lots of posts, people who frequent here and post regularly.

    The first ECU must be a bone stock ski and no hardware modifications.

    The 2nd ECU must be on a ski with both air intake and exhaust modifications and supercharger modifications up to 15 psi boost.

    The 3rd ECU must be on a ski with both air intake, exhaust and supercharger modifications up to 17 psi in boost pressure.
    No stock superchargers or stock pump impellers need apply

    I can tell you that mapping is perfected and the results are very good. We are looking for a few forum members to try our tunes free of charge and post about their results on the forum.

    The first three people to post on this thread and meet the criteria above will get our consideration on programming your ECU.

    Thank you!
    Jerry

    Friend of mine has SHO with stock boost but intake and exhaust. He is a lurker not a member. He would like to do this if possible. I will get him to join and wrote a review or do it myself since I will be installing it and testing it. Let me know if possible. Thanks

    Chris, thanks for the offer, but I really need someone with boost modifications to fill the spot for the 2nd ecu. I do have some nice supercharger upgrades available through the store if he wants to buy one?

    I am running the V-Tech stage 3 with fantastic results. The acceleration throughout the entire RPM range is what I like to call INSANE!!! I have been doing some testing and tuning with the V-tech and the R&D R3. This past weekend i ran both ECU's back to back and can tell you the without touching the ski other than swapping the ecu's I gainded 200 RPM's, and the acceleration gains were noticeable as well. I was only seeing 8180-8200 with the r3 and right after installing the V-Tech i saw 8380-8400.

    I will keep everyone posted as I continue to tune the ski.

    My VXS is bone stock. I have a GPS mounted on it, and I have access to a radar gun.

    When a tune becomes available, I would be willing to do a series of test runs to compare with stock.

    I will try to convince him to get a wheel but he is nervous about reliability
    I was thinking he could be the stock position. He has the Tommy Jordan exhaust mod and a cone filter on his stock Intake elbow only

    I guess I fall under the second option..... How much exactlly do these vary from R&D anyway? Just a hell of alot more timing with the V-tech or what?
