I got my remap done by ADS in Preston (REVO approved) on Monday...been going on about it for so long now and I'm well chuffed. Got everything I expected!
I mostly notice an increase in performance above 2400rpm, it's allot smoother in 1st now too, more eager to accelorate. Blasted a few people and still managed to retain over 40mpg on the dual carridgeways.
So my opinion would be REVO all the way!
