Since the Prosport RR day I had the full exhaust made to 3" which certainly made a big difference and also fitted the PCV mod which allows the car to hold another 2psi in certain conditions..
Also Regal have BIG fans when dyno testing the car, and they run the bonnet open, makes a big difference!!
As I said to you on the Prosport day the intake has never been that hot before, after a drive on the road its very cool to the touch, because of the heat tape and the CAI that I run..
If you check out the graph, the dashed line is the car with the K04 turbo, pretty nice curve really..
