I realize that I am reviving an older thread, but I am hoping for some fresh perspectives and data?

Is the Renntech ECU tune ($1,200.00) the way to go? I do like the idea of actually having the ECU remapped, as long as there are no warranty issues.

Upsolute ($699.00), Evolve ($1,063.24), and maybe someday Dinan all have ECU tuning.

Chip Express ($649.26), JBD ($343.00), Race Chip CR Ultimate ($679.00) appear to be "piggyback" software that Tricks the ECU.

My primary motivations are:
-More usable power
-Better MPG in daily driving
-Long-Term reliability

Thanks in advance!
