Power Commander or Power Card?

[papasmurf]

I need some thing for my S2R800 w/ full Arrows & open air box. What has worked the best for members on this board; Power Commander, Power Card or other and why?

I used a PCIII USB when I had my S2R800 with custom pipes. I had it tuned on a Dynojet dynamometer and it worked great...

I have a PCIII USB on my S2R800 with midpipe, termi's and open airbox.  I have a customer advance map (one map for front cylinder, one for the rear).  It works great and totally changed the bike.

I'm using a Techlusion TFI (slightly less adjustable version of the Powercard) on my M800 and was absolutely stunned by the difference it made.  Way more power, way more torque, (both measured by my pants-seat) and it's shade-tree adjustable, no dyno needed.  Maybe it doesn't extract the last HP, but that's OK with me.
