Surprisingly with more BHP and the T4 it also a lot more driveable. I also run 235 Toyo 888's on the rear which helps.

The final on road mapping was done with a good experienced ex mountune man

It doesnt really suffer from too much lag due to the weight and the power delivery is much more progressive now with the T4. I dont know what power its running but should be kicking out what you would expect from a good proper built engine with all the usual tuning bits, 850cc's and a T4 running around 26PSI. I could turn the boost up but seriously it really does not need anymore and its reliable at that level. Would imagine it produces a good genuine 450 BHP??? But dont care really. At that level it still gives around 650 per tonne!
