I picked up the Aero Racing manifold and full system from the factory on Monday.
I'm still getting low 30's but there's no doubt that my engine has loosened up significantly and is now just over 7000miles.
I never had the original upgrade ecu flash, but once I've fitted the new system, I'll pop back to the factory for the Clubsport flash.
Yesterday I got the exhaust off, but I left the manifold until Saturday because it doesn't just lift out.
Obviously I'll take some pictures and do a How To, as I go.
This way, having done 7000miles with a standard set up, I can compare the new system before the ecu flash, then on the way back from the factory I should get a clear idea of the changes.
