Scott, Batey who you bought the car off is a good friend of mine, and I was with him when his car was mapped at NMS. He asked Karl to map it so it was quick'ish but as safe as can be on the gearbox. Karl said he could make it around 400/400 because the engine felt strong and just wanted to rev.
I'd give NMS a ring for more boost, 36 psi will get you moving!
