hi Ant, Im asuming you have submited the RR print out
http://www.s314kba.co.uk/leaderboard/
looking at the power you getting from the turbo and boost your set at looks like you have the sme problem I did.....
My car is a Auto to manual convertion and when changed the TPS lost a 5v feed, you can tell if you have the auto TPS coz it will have 4 wires going into it.
if you check and its is I can explain how to fix the problem as you should be making 180bhp plus at that boost pressure and hybrid turbo.
