    I've had the VXR reflash on my both of my skis for 55 hours now. I like it fo sho. More accel to be had for sure and that's always a good thing.

    Hi Jerry, the description for the stage 3 says you can run 17 psi with this tune
    and a RRFPR is needed for i would say 18+ pounds of boost? so you dont need a RRFPR for 16-17 pounds of boost? meaning a C5, E1, or ET 15.5 making 17psi? im wondering as i may upgrade to a bigger wheel but dont want a rising rate.

    thanks.

    Jorge, despite what the product description from V-Tech says I would still recommend running a RRFPR for anything over 15 psi boost pressure. There is no such thing as a reflash that is "spot on" for every ski so having a RRFPR will enable you to fine tune for your setup.

    When I was looking at the R&D re-flash, most said to go with the Stage 3 even on a stock ski. What about V-Tech? Is there any advantage to running a V-Tech Stage 3 vs Stage 1 on a stock ski?

    The only advantage would be that you could grow into the R3 or Vtech Stage 3 tuning at a later date if you decided to add modifications as those reflashes are mapped for higher boost levels.

    Would there be any disadvantage? Would a stock ski run too rich with a stage 3 program at WOT since the ECU is expecting higher boost pressure or cooler air from an aftermarket intercooler?

    No not at all. The ECU will be pulling from a lower fuel table based on the lower boost pressure input of the MAP sensor. The IAT sensor also comes into play here.

    Jerry I agree with you , When I had the stage III V tech reflash done, I have to use RFPR as rising not even static because it was very lean on the stage III.
    I must say that all the ECU reflash regarless no matter what brand Vtech or R&D you must have RFPR install not all the ski are the same otherwise you cound have damages on the motor.
