jamie has worked on ALL my cars in the last 6yrs and never had a problem. as for mapping my car was mapped there and yes using the rollers and same again perfect, cold start perfect, mid range perfect, full throttle perfect. can'ty fault them in anyway. AS for chav's I own a saph and it runs a jamsport sticker to show my support. As for Lee R guess he can't say good things about them as it's local competion

One thing I'll say which maybe pisses some power figure chasing customers off is that jamie will not tune a car to make the figure wanbted on the rollers, he'll tune it to the best and the safest to the parts fitted and the customers budget.
