I'm which of the handheld programmers is best? As much as I'd love to get a nelson tune It doesn't seem practical for my application. I intend on changing rims (and dia's) between summer and winter and sending the pcm away sounds like unnecessary downtime to me. I live in cental Canada making shipping even more of a PITA. So who has the best handheld? Jet,Granetelli,Hypertech,Crane, any others? who has the biggest real world hp gains and trans adjustability? Is there anything out there more advanced than the handhelds? Something that'll give me even more bang for the buck. Thanks
