Mine was run at a place in chesterfield, brand spanking rollers and a pukka bloke and i was looking for some power i thought i was misssing, as it happened car was perferct and first time it was ran up it made 200 dead but we did multiple runs as we were checking afr's etc but we actually changed nothing at all yet each run it made just a nadge more power till the final run when it made 205 bhp...thats not the only time ive seen this either, you always need to do at least 4-5 runs imo to start getting a true reading and roller days only run once, twice at best.

I agree dave. A few runs are necessecary for the rollers to adjust for the car in question imo. Likewise i thought i'd be adjusting some parameters to gain a few horses when i went down to see matt but as it happened it made 210 straight away and ended at 213 after a few runs. I think matts rollers are pretty accurate as he reckons he put on his audi a3 which is factory spec and it made the exact figure the company quote. As we all know though rollers are funny things and can be different werever you go.
