Finally got my boost control sorted and did a E85 tune on it and it was pulling high 390s and low 400s all day on 19psi. I'm still only turning it to 6000rpm at the moment so it has a few more revs left in her. Considering the auto slips in 3rd after a few runs and the convertor is soaking it Im really happy just to break the 400's. Its a handful with what becomes a 5000rpm stall and a 1500kg car.

The GT42r is just starting to come on at this boost so should be much better once we go past 25psi, so Ill drive it like this for awhile then change auto and turn it up some more.

Still the same power but now its managed a
10.36@144mph with a 1.8 60 ft with a ton of wheelspin. The only other run of the night before the axle broke was a 11@138mph

Pretty happy with the mph considering it only shows 400rwkw.
