How well do they live 6500/6700 my motor has some hours on it 500ish? Should I upgrade compresssors before raising it? I really like running 28p props but the limiter keeps getting in the way. Haven't ran a 30 p I have liked nearly as much yet.....

so so I kinda want to **** can the limiter this winter

for just keeping it off the limiter is all that the upgrade is good for. i had it done on a pair of 300xs motors. i did not notice any more speed or acceleration. but went away was going into gaurding mode at wot. every now and then one motor would hit 6400. and at that speed i never would here the beep. it would go into safe mode. when it did that it would turn rather quickly and scare the hell out of me. i tried of smaller props and motor sounded like it was going to come apart at 6800. xs motors seem to fall off at 6300. but the price was worth not hitting the safe mode.

Don't think it would help unless other work internally like port work. MY 300xs turns the same RPM with 28 or 30p props. They just don't like to turn more than 6000-6200 RPM.
