the engine is running very rich & is only really happy on boost, probably due to the restricted flow through the cvh head in comparison to the cossie head, my power figure was crap on picking it up from pts 175 bhp & same torque, this was due to the rotor arm being set incorrectly (wasn't set like that when i took it in!) i set it correctly & it goes so much better now, but ive not had a power run since as im building a 2.1 zvh to replace it, then off for a proper live map
