5.7 Hemi Conversions - XVMotors? Arrington Chip Killr? Other options?

I've been working with Plum Floored for a couple months as a joint effort and he offers Inertia parts and I offer his. One thing coming from this is we've combined his custom wiring harness with my experience and connections in tuning the hemi trucks and LX's. Whats coming out of this is a harness combined with a 05 truck PCM thats flashed to work in an old school car and has the 6.1 base format in it. Were going to set it up standard for a cam which will probably be the SRT Max 112 but the cool part is it will accept a diablo predator so we or any tuning shop that has CMR can fully tune it for other head, cam, stroker, boost or nos combinations. You can email tune too I do about 20 email tunes a month. Since it's baised off the factory PCM you would get the benifits of the factory PCM. I tune hundreds of LX's and trucks this way with lots of different cam, head, injector, storker combos so I have a big tune library to start from and then tweak the tune in from their. Point is there will be alot of flexibility in this combo and were going to bring it out for I'm thinking just over 2K and it uses all the factory sensors that you normally get with the used engines floating around. So it's alot of bang for the buch and allows lots of mods. Another point is you can control the timing like you can't off a distributor based system as on the hemi you can make max power at about 24 degrees advance at 3K RPM but you have to back it off to about 20 at 4K and 4.3 K to avoid detonation then you climb it to about 30 in what looks like a logrythmic slope. You can't do that with a distributor. Really, you can't come close to a good performance tune without full knock sensor support like this system has because the ring lands on a 5.7hemi are only 0.100" thick so if your hearing knock it's probably too late. With the factory knock sensors like the factory PCM uses you can tweak the tune to the best possible tune safley and still have protection from the knock sensors if you get a bad tank of gas.
