are you running a p3.28? I have heard they run well, just a tad picky when it comes to holding a consistent tune, apparently that is something Jay addressed himself, along with some timing issues and crank tolerances, he was completely behind this new design from what I hear, Rob @ Nitro House knows his stuff, so I believe him when he says they are COMPLETELY new. The rumor is the Jammin.21 is a re-badged p7evo.21, and the Jammin.28 is a re-badged p3.28, not the case from what I hear, I think I may go with the Jammin, it just seems like a "wiser" investment then an SH based motor....as Mike stated in another topic, they run great, then they go BOOM! As you stated, Picco's run forever, and I can actually get support on this mill vs. the DPS. Any other opinions floating around out there? plz share, and ty for the advice Rob
