Thanks for the replies, Highpower want £537 for the kit and £300 for fitting it, the progressive controller is a further £300 on top but this turns the kit from a single shot kit into a fully controllable one where i could have 100-150bhp jets fitted, and use it safely, AFAIK it does this by means of you programming the control by telling it what percentage of power you want after various times into the run, MONKEYMARK how did elvington go yesterday, did the cortina get away without any problems this time, did you run, i was going to turn up again but i had a 4Oth party on saturday night didnt want to risk driving.
