thanks guys for all the response, I can see that there is plentys of knowlege to be gained from big power, anyway got a call from clive yesterday and he said he has spoken to the guys at dyno and they have given him some more indepth settings for the rolling road and seems to think that this should solve the issue, sounds good I will keep you all posted,thanks again everyone
I seem to recall that another issue is that Porsche Stability sences that the car is moving at X road speed but has Zero loading on the dampers NO Down force so the ECU say that is not right so no play!!
Porche tunners must have a way over it like Simon has for the BMW
