It might be pushing it. I would be doing everything possible to keep IAT's down.

The increased compression of the na motor will give you problems.

Thanks for help and advice mate very much appreciate it, I'll do some logs starting with a standard pulley and see how it goes.

Just buy the top swap tune from Mace, it's not expensive. You might have to contact them directly.

I got in touch with mace and they do sell top swap tunes, but not for 10psi pulley only for a 8psi so it looks like he will running 8psi.

Pop in on the dyno and get a baseline test. Mace sold me a tune and its good, but just a tad on the lean side. Not enough to worry about but if I have it retuned I will increase the fuel ratio slightly.
