Yep thought so, mate had VERY VERY bad experiences with them in terms of engine building and general work etc... so wouldnt touch them for that.

However a few mates have been there for dyno runs and seemed to be about bang on actually. Modded 325 BMW gave 178bhp, mates virtually standard RS Turbo gave 145, mates 1.6 punto gave 105.

Why do you ask?
