Anyone else here running a crate LSX454 with LS7 intake from Jegs?

Noticed mine is surging at low RPMs.

Did you have to tune yours?

I'm no LS mechanic but I've read that some big cams or larger throttle bodies can cause surging that can be tuned out.

I had a similar issue due to my cam and after consulting many, I was told that I would have to live with it because of the factory ecu -- I went with the Holley setup and now the surge is gone.

Did you have a crate LSX454?

Who did you get to sort out the tuning with the Holley setup? Did you use the dominator? Was it an easy fix?
