V-Tech Stage 3 Tune Results !!!!!!!!!!
V Tech Stage 3 tune
Stock Ride Plate w/ Jims Cut
Skat 13/24 w/o pitch
FPR set at 53 Psi
High Perf Fuel Pump
I didnt have a Tiny Tach or any Rpm meter, didnt have an Air/Fuel Ratio gauge, so i couldnt tell if the ski was running good, i did notice i wasnt getting enough RPM to turn that Skat 13/24. The difference is huge with this V Tech Tune My highest Pass was 77.6, now the ski has the appoiment with the mechanic to be tune property on Monday from there i will let you guys know what happens.
if you guys have any advice, im all ears, thanks

What was your speed before the tune?

Note - the ski has not been tune properly so probably im leaving most of the miles in the table,
jerry my Max speed on stock wheel and stock pitched prop was 70 to 71 Mph,
But you notice you have a different ski when acceleration comes in, hugeee difference,
I recomend the V Tech Tune

Your gains are huge for the first time to the water with no tuning. Get note of your RPM's and then pitch the impeller to run at 8500 and 80 mph won't be a problem for your ski. Also check the AFR and adjust the rising rate fuel pressure regulator accordingly.
Keep us informed and congratulations on the new speed

Speed is the goal but RPMs and AFR should have been a requirement for this testing....
