Default SDPC Budget Forged pistion kits any good for FI?

Ok, so I'm gona build a new motor for my truck. What I'm wanting to do is build an iron block 347 out of my 4.8. This will be a turbo motor too. Here's what I have, the block that's currently in the truck 4.8/5.3 bored out to 3.898, a crank out of a 6L, a set of ls2 rods and a set of 317 6L heads. I figure with flat top pistons this will put me in the mid to low 9's for compression with stock gm gaskets.

This is what I'm looking at for the pistons. Anyone have any experience with these piston kits from SDPC? Are they any good? I will have the rotating assembly balanced and will be using ARP heads studs. I also plan to run this combo up to around 13-15 psi of boost. Think it will hold up? Sound like a good budget, forged FI motor? Please let me know your thoughts.

If I were planning to run 15 pounds of boost, I think I would go with a set of Diamond pistons. Speed Pro make good pistons, but the Diamond pistons are a proven item for boost.
