and did you have any issues one you got it all on and the software loaded.. did you use the preloaded tune that came with it?
My only real experience is with Vortech. You'll want access to a lift. Trying to do this with a floor jack while on your back on a creeper will not be any fun and you'll be inventing and expressing a lot of new colorful adjectives. The instructions were fairly well written with quite a few photos. I would have liked more. Still you need to read through the instructions several times, think about them and take your time. It was all pretty straightforward. The toughest part was drilling the crankshaft for the pulley key. Stock engines have a pressed on pulley. The kit comes with a jig to drill for a key to keep the pulley from slipping under the extra load of the S/C head unit. The crank is extremely hard and it took several drill bits. Someone who installs these frequently can do it in 10 to 15 hours. A first timer should realistically allow 15 to 25 hours. Everything with the Vortech kit was precise and fit really well. I imagine a Procharger install would be somewhat similar but can't say for sure. A roots or screw type S/C will require that the intake manifold be removed as it's replaced by the S/C. It's more involved than simply bolting on a centrifugal system.
The only issue I had was that I had to remove my old strut tower brace because of the after-cooler. Speed Logix makes one that clears pretty much anything you want to bolt on top of the engine. I just had to modify the bracket for the after-cooler reservoir and everything was good.
Yes, I use the preloaded tune that comes with the kit on a Diablosport Predator. It's a very reliable tune leaving a lot of safe head room in the AFRs. There are tuners who can get more aggressive and make more power but getting too greedy can play havoc with stock internals.
Let me know if you have any more questions.
