Evo f**ked me over too... not quite $4000, but held my car ransom (looooong story as to why it ended up at evo) and went back on everything they said. The sad part is, Ben also tuned my car when he was with Evo (back in mid 2003)... I cant really say anything except I was utterly disgusted with the end result.
HOWEVER I have talked to friends of Bens who told me while he was with Evo, they pushed him to just get the car in, make a pretty power figure and get the car out... dont actually spend any real time on it. Since he does his own thing now, he takes alot more time with the cars setting them up properly and I have not heard a bad thing since.
Either way with regards to tuning my car wont go to anyone but Ed... How can I argue with someone that has the most power fc and motec experience in Canberra, has access to a dyno dynamics certified shootout dyno, has both the genuine Apexi software and the Datalogit software, and hasnt made a car go bang yet?
Just my $0.02...
