about what I figured, thanks!!

 

Why not have synergy install theirs???? Works like a charm.

 

I know it does. I have to take my car down to Synergy sometime in the next couple of months to get some more work done. I just didn't want to do the 5 hours round trip for a 2 step.

 

I installed the MSD 2 step and my backfire issue is 100% gone. This thing works perfect. I made no other changes to the car or the tune (apples to apples comparison).

I'm thinking the Lingenfelter units are just over priced junk.
