Hi & to the forum. So many factors can make a difference including the dyno. I got 273 from my 276 when we did a dyno day, we never found out what whp was though as the computer got fried by Ians' K1. What fuel you putting in?
Ian, these guys are really good. Did my mothers car recently and have done her neighbours car more than once. Very reasonable on price as well. Also did my Rays recently and they came out superb. http://www.wheelsmartrepairs.co.uk/
IRC didn't Amy say the magazine wasn't to blame and that a lot more was to come out about the situation. Either this is correct or they have really fed her a catalogue of lies and bullshit. Whatever the truth they certainly haven't acted in any sort of professional way.
