Sorry. Videos were the last thing on my mind today. I just needed to get the car done and out the door. I did see John with his camera take video. Maybe I can get him to upload them to a Youtube account.

I used to have a QTP electric cut out on my car. Man that thing was awesome. I had it right after the header like where the cat should be. It was f-ing loud. I broke 2 of them, then when I lowered my car it was not an option any more.:icon_cry:

Little to no gain.

Turbo cars hate back pressure. Most of the 40 hp gain came from the increased boost due to the decreased back pressure against the wastegate. I am sure the cutout itself help some with power. My guess is 10 wheel.
