Apparently my fiance was bored and decided we needed to dyno my HHR, so he put the stock tune back in, ran it on the dyno, then put his tune in, ran it on the dyno again unloaded, then loaded the dyno and ran it again. Here are the charts and then the video at the bottom is of the last run.

I tried everything I could to embed the video and nothing worked, so yeah.

Interesting results there, some definite gains across the board, just as long as his boredom doesn't turn into "Honey I Blew Up the Engine".

Nah, he wouldn't do that, and even if that does happen we have something planned anyway We also found out that the exhaust has a crack in it, and since it's only been on the car for a year and a half we have to call Magnaflow and see what kind of warranty they have. I was pretty impressed, since his tune also made the gas mileage better, I went from averaging 26-30mpg to 32-36mpg on my 7 hour drives home.

Edit: Apparently he was having problems with the torque converter not staying locked like he wanted which is where all the weird dips are from on the charts.
