I gained 20whp peak whp and anywhere from 15-25whp throughout the powerband JUST from an Uprev tune. My AFR's went from ~14.5 before tune to ~13 after tune. A 14.5:1 AF ratio is pretty lean and is not good in the long term.
and FYI, $500 includes 3 different E-tunes from Uprev.

OP, your tuner probably knows this already but make sure your ECU code has already been cracked by Uprev. If not, you'll have to do an ECU ROM dump and send the files to Uprev and wait till they crack the code. Luckily my ECU part number was already cracked so I was able to reflash my ECU instantly.
