personally I think its been set up wrong, im sure that you can use the same setting on vpower and momentum
i am happy to drain this fuel, fill it with v-power run that tank through, fill it again and go back and ask for them to set it up again and see if they can higher the timing.
i have read (as im all over the place now looking for info) that some remaps can take a few miles / hours to "set in" ? anyone else heard this?
