Well if you are looking into the STS setup, I recommend it. I had it installed as their Guinea pig back in 2004 when the new 3V's came out. I had a helluva time though getting a tune, everybody (Roush, ATI, etc) was hush hush on their tuning for their R&D for their kits. So we did a basic tune at Dallas Mustang. Long story short, I blew the poop out of my motor about 15000 miles later having fun. The power was great, noooo lag due to the fact that you have a V8 with gobs of lowend TQ from the get go. Setup was easy, don't know if they changed the little resistor or not for the oil pump, the gold doodad that changes from lo to hi flow, but I had a scare while cruising through the desert when my oil pump alarm that comes with it went off, and I looked like Spyhunter going down the interstate with the plumes of oil coming from my exhaust, so I cut out the resistor and spliced the wires together and kept the pump on hi fulltime. No Damage, but man it was scary. Since then, I have had JBA build me my new motor here in San Diego, all forged internals, ported heads, and so forth. Just recently installed my Whipple Supercharger pushing 10 lbs. Running 389 RWHP and 441 RWTQ with a very mild tune. But I pull away from my buddy's Lightning with ease.
Now that they have completed the kit, your install should be a helluva lot easier, no need to cut and measure and bend the tubing yourself. I did a top mount intercooler setup like the WRX's have due to my ram air hood. Was pretty sweet. Hopefully this helps you in your decision, loved my turbo, but the Whipple screams when you punch it, both sounds are sweet.
