Hi rossco thanks for all your replies my friend..

The motor has 40k on it and it's pretty much a virgin..
Yes the p20 I'm told will be lagierr but this will be offset by the following..

E85 allowing more timing.
Heat wrapping the exhaust or ceramic coating to reduce lag time.
Electronic boot controller ( I'm told that's the beauty of the apexi AVCR)

So yes P 20 will be lagier but I have to increase the MPH some how unless there is a better solution..

I had no idea the power fc comes with an electronic boost controller.. How does it compare to the Apexi AVCR , how much is it and where can I get one..

Regards pk
