No comparison between the jb tune and the Procede. If you want a tune (and not a boost controller), get the Procede. It will provide heaps more power, better drivability and more engine safety. The cheap and dirty approach of just turning up the boost and hoping that the factory knock sensor will save you doesn't apply to the n55.

Frankly I'm surprised you're turning the boost so high on the N55 without even basic fuel control. But be that as it may at 2-3psi over stock with the JB Stage1 the motor would benefit with more advance not less.
Also that 113.1mph run is nice but the car did 106.5mph stock. So the tuning and big IC added 6.6mph. It remains to be seen if 6.6mph is added consistently with those two mods. The JB Stage1 on 100% stock cars has been adding 3-4mph. Not bad for $379 and the overall tuned driving experience is great. Night and day vs. stock.
