If so what pulley do you have and what pressure are you seeing?

I've got an Alta 17% fitted and at WOT i'm only seeing 14-15psi, now i'm sure it should be higher leading me to think a 15% may have been fitted by mistake.

If you've got a newer teflon coated supercharger can you let me know the pressure you're seeing as well.

Facelift model and on the dyno with 15% I seen 16.67psi, after fitting new RMW head I see 14-15psi on boost gauge (not been at WOT yet though)
