Okay so you have the mp box same as a msd and the Orange box? If your running the mp box same as a msd then the Orange box isn't even needed. If your on just a factory ignition system it is always better to have the hotter spark especially in boosted engines, yes 5lbs isn't that much which is a good thing since your comp is a tad higher not much. The 9.5 comp is fine for boost you just can't go as high as say a 8.5:1 but it's a toss up, I knew guys on their srt4 with big turbo that ran 10:1 comp and kept boost down low and make good power or you can run lower comp 8:1, 8.5:1, 9:1 and go higher boost but make about the same power it just boils down to the tune. Meth is always a good thing keeps the intake charge and combustion chamber cooler thus making a little more power plus it takes your pump gas say 91 octane and makes it 116 which again better for boosted applications as well.
