Procom CDI Rev Box

[Rig]

Hey guys I was looking on eBay and found a Procom CDI Rev Box for my 525. Does anybody know anything about them? It claims an increase of 1000 rpm's, better spark and a different timing curve. Is this to good to be true? And would the extra rpm's hurt the motor? Thanks!

I would stay away from Procom CDI box I have seen too many engines blow up with there boxes, very poor quality control

Thanks for the info! Is there a box out there that I don't have to worry about? The only mods I've done is pipe, airbox and jetting. I just need a little more to beat my buddy up Choke Cherry!!
