Had John remap our ECU and Jim at Star Performance fit a mid and back section to an already fitted Magnex front box. The car felt so good we put it on Jim's dyno and got the results below.

 

very nice,looking at the figures a full exhaust system should give 20-30bhp so the chip has given about 25 bhp,iam becoming tempted again having just persuaded myself that my p1 with wr backbox and prodrive brakes is enough.any other mods?
