Procharger tensioner system
The J bracket
the stainless hex stand off that holds the idler pulley on
your stand offs
The easiest thing to do is send in your entire bracket with all the hardware...don't take anything off or apart....we'll return all the necessary pieces back to you...

If you decide to go with the steel J bracket, you will need to purchase the stainless hex standoff as it doesn't come with the bracket.
My neighbor was breaking / throwing belts on his D1 all the time until he put one of these on.....no problems now.
You guys will be happy you bought this!!!

ATI balancer GP price for AC is $440.00
Didn't offer a GP on the fan shroud, but if you purchase with the tensioner I'll take $10 off making it $389.
Assuming we get one more, your cost for the entire package will be $1434.00 without the install tool. Add $38 for that. Plus shipping for all. Not a bad deal!
We've got 3 fan shrouds left on the shelf ready to ship for anyone else interested... 
oh and mine is DEFINITELY slipping with the 3.4" pulley (tension is at 19).......I am running 2 bar speed density so my tuner (Frost) and I can log map sensor values and boost varies between 13-15 psi
I ordered a reichard pulley to see if that helps

Thats not belt slip causing the psi to jump around like that on my graphs, the graph on the 2nd pic was the exact same setup with one change that had nothing to do with the belt.
I highly doubt you are seeing belt slip with a D1SC and a 3.4 pulley unless something is wrong. I never seen any slip at all with that pulley combo to 7400rpm in cool weather. I could run within .05 and 1mph all day long, that doesnt happen with slipping belts. Not saying its impossible to have slipping belts, but I have had three SDCE setups and none of them ever slipped with the D1, F1 is another story but it wasnt anything severe.
