Thanks guys.
Here is a more recent photo whilst up RCM. We put the thing on the dyno just to see what it was currently running at. No chasing of power figures or no mapper present and running on V Power only it made 548 bhp.
Feels much better since ditching the coil pack and opting for single new age ones.
Still using the GT30 Billet Wheel and although a have a brand new GT35 in a box the GT30 delivers the power perfectly. There would be no gain using the 35.
