This has probably been covered before but which is better and what are the prices of them? And what do they do to fuel economy? I remember reading a post where someone with the REVO tuning didn't get more than 24MPG, just been on the upsolute site and they say the fuel econ stays the same (under the same driving conditions - is this just a get out clause? As you can't drive the same with more power).
Also, I know of wheelbase in Hersham, Surrey that do the REVO tuning, what about somewhere in Surrey that does the UPsolute chip? Anyone know? I've read the UPsolute one is ?300 (is that fitted) and I know the REVO to be about ?600 with the VAT.
Thanks.
