I am on the fence as to which to purchase? I realize that the JBD is a "piggyback" fuel map, while Upsolute is an actual ECU re-map.

Upsolute is $375.00 at a local dealer.

JBD is around $279.00-$299.00 from what I see.

Looking for more usable power, reliability, and no appreciable loss in MPG; realize this is largely the "right-foot" factor!

All of the 335d threads say fairly good stuff about the JBD, but little is written on Upsolute? I do not feel like paying Renntech $1,200.09, or Velos Designwerks $899.09.

Thanks in advance!
