Strange way of going about things to me.

its running 20psi mate ,and had the management from my cvh turbo engine its just been remapped.ps i made both the manifolds.

think 400bhp and torque is a good result but i'd have a word with your tuner if thats the print out you've got.

The torque he made though, just to put things in perspective, is sufficient for 350bhp @ 8000rpm

So to make what will is saying, you can still allow for the fact the VE drops at revs increases and still consider it reasonable on 9psi

T34 will be the next upgrade i think, which will be when the current t3 shits itself or when he gets bored and wants a bit more.

It certainly wont be revving to 8k thats for sure, its only got standard cams, valves and head, the tweaked bits werent required for his power aim.
