me and corby have just been and put the cars on the rr . i have revo who quote over 200 bhp with the map and corby has one of angel tuning . mine is the 1.8 t and corbys is the fr tdi . corby got 165 bhp and just under 300 ft lb tourque and i got some strange results my first run hit 189 but the guy said the heat sensor had fallan ontop of thr rad . then every run after that it went down they did agout 8 runs and it went from 175 to 162 in the last three runs . i rang revo and the guy said it could be the diverter valve split and i should upgrade to the forge one . After the rr sesion we went for a spin to see how the two compare we raced from 40/50 on and mine kept slightly pulling on the tdi by a few car lengths but if the rr is correct surely the tdi should quite easly pull on mine 165 bhp and 300ftlb tourque against 162/175bhp and 225 ftlb especially racing from a rolling start where the tdi is at its best
