You're going to love it. I haven't even tuned mine yet and I'm running 24 lbs of boost on crappy Colorado gas without even a hint of detonation. It's a pretty impressive system.
I have to be honest I didn't install it myself. I took it to a local shop and had them do it. They charged for 3 hours ($180 bucks), well worth it to prevent me from screwing it up or having to spend 15 hours on it.
You just made the best decision and or mod for any street car. It can also save your ass alot of money. My brothers and I all got our setups at the same time- we met at my house and each installed'em in 4-5 hours. And this was doing things right with CLEAN installations and wiring.
YOU WILL LOVE IT!!!
