When I installed my CircleD 4200 stall, there were no issues at all. Didn't need a crank relearn either, just worked out of the box, don't know how wild your cam is though???. Difference here is that I already had my PCM and TCM tune optimised . You only have a 2600 so I don't think you'll have any issues either (depending on that cam and how good the tune will be), as Joecar said to me, install it and try it. Search for the relevent threads, they're in here. Good luck, I'm sure you will enjoy the stall.

I'd say get your tunes sorted first though. Post up your spec's including cam.
