well i'm not changing any pulley just spinning it higher.. right now at around 6800rpm i'm at 15psi on 91 and 100oct. so for my 100 tune i'm hoping to spin around 7500rpm at like 17-18psi.. we'll see if she makes hp up there tho.. it might drop off and in that case i'll just stick with it until i go A/A in a month or so then i'll put a 10% o/d pulley on it. that should be fun.
Nice!!! U have the HRE wheels on there too right?
