I see that a number of Scoob and EVO tuners are now switching to high compression.

I have just changed (Scoob) to high compression and the engine is awesome.... still managing 2bar boost on a straight VPower, but have much better response and more power at less boost and ignition.

Using a GT30 core we managed 485bhp at the fly on low boost of 1.45bar

and

486bhp at the HUBS on high boost of 1.8bar.

High compression is good.
