Seeing if anyone besides me has actually done a before and after with the JB+ Stage 1 from Berger Tuning? At default setting I picked up 16whp, raised the inside dial(s) two clicks and got a total increase of 25whp after emailing back and forth many times, they told me to keep raising it until I got 50+ hp increase, all the way at max made no difference still 25hp increase. Disappointed was an understatement. I've owned and built many cars so I don't allow the psychological typical "I spent money so it feels faster" happen to me.

Current mods: resonator delete, muffler delete, charcoal filters removed.
