I decided last minute that I wanted to really learn the ins and outs of this project and I'll be doing the install myself with my best friend. Probably will take us 2 weeks with work and all but should be a great experience.

I'll be sending out the ECU stuff to Sam tonight.

EDIT: I should say, I am confident its going to work fine with the HD cooler, but I'm also going to go a bit custom in the placement of where it goes. I'm even entertaining the thought of the Zele front bumper for the purpose of more air flow/different placement possibilities.

The reason you want to switch back to the stock cat is it because too much air flow and not be able to hold boost? Because I am interested in the SC kit, but I'm running test pipes too, I don't know if my exhaust set up right now is the best for the SC kit. You think switch to HFC will work?

You'll find that with the cats, you make more hp with less boost. Put the more restrictive cats on and boost pressure goes up, but make less hp. Correct me if I'm wrong, but more power at less psi boost is better/safer.
