Need to separate benefits of each mod. Exhaust and dynojet kit gave you 20-25% more power which is noticeable.
Airbox gains zilch. PAIR only functions on coasting, so zero performance benefits in removing. I have it on both my street bike and race bike. Popping on race bike was caused by clogged diaphragm in coast-enricher, tiny piece of grit smaller than grain of sand did it. Street bike never pops.
You have to ask yourself how much is your time worth? How much at your hourly wages are you wasting? For me it's easy because it's time per second saved on track. For much less time and effort, i shaved stock 375 down to 320 in a weekend. That's good for about 5s/lap. I'm not going to waste that much time and effort saving 1.5-lbs but needing 20-hrs to troubleshoot PAIR. Hell, i'll just spend one of those hours working and buy lithium battery to save 4-lbs instead.
