Reprofiled cams don't make any more noise, they are fine. No different to any other cams up to a point and then the hydraulic lifters can't cope with how much material has been removed from the cams, then you need solid lifters. But there's nothing wrong with reprofiled cams
I've seen andyman's results and for the price of them you can't go wrong. Compared to the cost of Catcams I'm surprised more people don't run them.
Anyway, is it going to be a case of live mapping or does one of the tuners offer a map?
