I have the DCAI and I love it. I'm in a position where I can get a good 500 engine almost for free! I can even put it in. Its just the ECU in my way. Lantana pretty much sent me step by step instructions once when I asked. I still have them. I live in MI, so I won't be driving for months, I'm very very patient and wouldn't care if it took a while to get running cuz of the ECU. If I could just get one in and all hooked up, I'd be ecstatic. That sure would be something to look at and think about while I have my coffee in the morning. Ahh so many options, and at 20 I feel like I'm running out of time to go with something. I think a 500 engine with the NW DCAI that I already have and an NW SRT all cat delete exhaust with the ECU tuned would be nasty enough for me.
