Does it feel like it picked up that much torque down low? That's quite a bit for sure...

Very nice gains there Mike! Congrats on a strong running setup. Makes me wonder if I should have kept my F13..

Thanks

I was out for a ride a few weeks back and stuck it at about 2800, and it threw me back in the seat pretty damn hard, caught me off guard. I was not expecting that at all. That is why I was so anxious to get on the dyno to see what it really did.

Are you speed density or running a MAF?

Also, do you have a lid set-up or something else?

cool, I love seeing good data like this.
Did you have any KR at 2700 with the pacesetters, and have slow recovery. it kinda looks like that, but not sure?
thanks

No, there was no KR. Some of the dips in there were just fueling issues. I did not want to change much from the street tune because the fueling was fine on the street and the track. The load on this dyno (5200 lb drum) was enough to change some of the numbers.

I will be going back after changing rockers and will fix those small spots to get the graph to look better though lol

Which Corvette headers fall into this category, the only two I can think of are the LG Pro's and the American Racing.

The longer tubes should also help the mid-range as well.

at 3100 it is 18 hp and 30 ft lbs

I finally got some more tuning done on it yesterday so all those weird spots should go away when I hit the dyno up in a few weeks. Just have not had much time to mess with it lately.
