I had the jb3 up until a week ago and I must say, it does miracles for the n54 engine. It adds roughly 50 - 60 hp on pump gas. With higher octanes it adds slightly more. I believe the boost is raised to 14 to 15 lbs....

I know what a JB3 is. I've done my fair-share of research on it but I've never seen a 335 jump from an est. 5.0 0-60 to a 4.3 with just the JB3. On N54Tech, I guy had downpipes, exhaust, maybe even an intercooler to get his 535 to a 4.2. Not to mention, running it at map 8 or 9 which required race fuel. But this guy said he had 91.

you can run 91 octane on higher jb3 maps....but not recc'd as those maps are designed for higher octane....so timing errors and perhaps knock retard will occur with higher maps on lower octane possibly damaging your engine...
