So heres the tentative list since we don't know really what the 100% problem is,
GM aluminum framed LIM gaskets
Coolant Bypass Elbow
New freakin coolaint.

They'll need the gasket between the super charger and the LIM also. Felpro is good there, as you'll receive the 2 coolant o-rings that GM sells separately. If they pull the throttle body, a gasket will be needed there, too. If not, you may want to do a good TB cleaning sometime in the near future. New injector o-rings would be a good idea, too.
03, can you edit your previous post instead of posting back to back in the future? Thanks.
Your shop may not have a source for aluminum gaskets. Don't go forward with the work until you have that worked out. Don't let them talk you out of a DEX flush, either. You are the customer. It may be SAFER for you to buy your own coolant and say 'Use this.'.
It was explained earlier that your supercharger replaces the UIM. You don't have the nylon (black) UIM. Nor do you have the EGR problems (erosion) associated with that. You are still prone to the same DEX/Nylon gasket leaks on the LIM though.

Well about 675 bucks later it will be all fixed. The guy kinda worked me on it not being the dex but I told him i wanted it done. So if they don't do it maybe I will do it myself. Any info that you guys can provide me if I have do to that? How hard is it I would assume not very at all. Since it was a long *** day at work I don't rember what they totally said so I will get that all tomorrow when I get it but I do rember something about the nylon gaskets. So i will get the whole 9 yards tomorrow. I am also thinking about getting new plugs but they wanted like 125 for that I said hell no. So where is a good place to get some new plugs for the ride. Thanks again to those who helped.
$125.00 for plugs??
You can get plugs at any parts store (Advance auto, Napa, O'reillys, Autozone, etc..) for less than $20.00 for the set.
I recently changed my LIM gaskets and flushed the orange coolant out and replaced with Prestone Mix with all. If you have a decent set of tools and a weekend to spare, it isn't that difficult. Just ask questions and take your time.

Follow these directions in this topic. It explains how to properly flush and fill.
