I have a busa powered car with a Power commander 3 fitted but i have changed the air filter and exhaust manifold and system so i just want it checking / Adjusting if nessecary.
Im located in Chester North wales,
Can anyone recommend any good rolling roads with dynojet expierience other than Holeshot and TTS.

Cheers

The problem you've got, is that you need a rolling road capable of running a car, yet somewhere capable of producing a custom map for the Dynojet power commander.

AFAIK, there are only three places in the country that have this facility. Two of them, you have already mentioned and the only other place I know of is PDQ in Berkshire.
