Here is a quick comparison video of my G8 before and after the tune. I wanted to get a speedo reading of just how much of an improvement the tune really is.

First part of the video is just with the solo mach shorty exhaust...second part is with a CAI and OVERKILLED!

SORRY FOR THE QUALITY

I'd say that's about right. Quite a big difference for sure. More of an improvement than I thought actually. I just wasn't able to tell how much until I put those videos side by side to see. It has a meaner deeper roar not only at WOT but just in daily driving.

Thanks for posting the video. It definitely sounds meaner with the tune. Looks like I found my next mod. Will wait until spring/summer to order.

Def seems quite a bit quicker.
