That will be decent Rob - I seem to remember reading somewhere that the characteristics and flow of this turbo is similar to that of the K04 turbo on the TFSi. Should make for a fun/fast transformation to your car
Should be yes, aiming to go from around 320bhp to 360+bhp. I've emailed David Manson about mapping it, no reply yet but hopefully he will be able to do it.
I will miss the hybrid GT2X, been an excellent turbo, but it's pretty much maxxed out now, so time to move onto a larger ball-bearing turbo!
