(cont) i have yet to see any more et or mph from going to a full airbox mod. i have run without the pcII, with the pc II, 007 map, 007 HARV map, all with no more mph. now, one thing i haven't done yet, is switch to 4 long stacks, so this may help me. but so far, full mod hasn't made me say "amazing I feel it" and pick up 2-3 mph in 1/4. im sure motorhead could put my bike on his dyno and find more power, but for that id have to travel (my bike only made 155.7 hp on a dynojet 150 on sunday)..has anyone that has had a pipe and partial airbox mod instantly picked up any mph by switching to a full airbox mod? i would like to hear improvements (track mph, not seat of the pants)in the real world. once again, nothing against motorhead, just speaking my own results from a full airbox mod... i will continue to test with this box (long stacks coming), but also will test with a partial-mod box also to find out what works better...
