Mike.....I did wonder about that to be honest - I have got a solenoid type boost control jobbie but it doesnt let you do it per RPM unfortunately...

Ballin - not really an option unless I can fit a different exhaust housing or fit a restrictor if its going to help?? I got it at a good price! LOL!

Chip - funny you should say that - it seems to get to full boost - 18/19psi even on part throttle - and feels just as quick if not quicker sometimes!!!!

Matt....its mine all mine...well not my arse obviously!!!!
