Maybe another slight engine tweak...

hmm, looking at those graphs, you've gained a small amount top end, but lost a huge chunk between 5k and 6.5k....

maximum of 30hp gained, right up at 7500rpm but you've lost over 40hp (and for a longer period of RPMs) in that lower area...

Not entirely sure that can be called an improvement!

It pulls far more progressively and peaks at the top of the rev band, both BHP and Torque, which I prefer.

I want it to pull like a train all the way to the top, not pull halfway to the top and then not pull as well.

I'd call it an improvement personally, it does just what I want it to do, from less boost.

Since it me that drives it, and me that built it, I'd say that my opinion is the one that counts.
