Found my stainless exhust was split apart along the seams at the bottom. Hoplfully that was the problem.

Call BD there is an updated muffler.

 

[Mr. Redrock]

That's how I found out it was bad. The new one is on.
It still has a low end bog. Makes it hard to cross creeks. Lol!

 

[MATCO]

What rpm?

 

[Mr. Redrock]

3800-4500 rpm. It's just off the get go. My buddy has 2863 GTX and it is better. Mine with a 2860 and Tial should be better than his, right?
I have been messing with the numbers but haven't got it to change yet.

Changed my extra rpm range to start at 3320

My sled runs really well with these numbers... Now and then i deviate from these a little if need be.

Try blending your AV with 91. My sled (nearly identical set-up/alt) will be noticeably sluggish on the bottom with too much AV.

 

[Mr. Redrock]

Found out my extra rpm and psi was off.
Runs a lot better now!
I can't get 91 in non ethonal were I ride.
What side of the helix are you guys running?
