Interesting, I'll look into it. ThanksFrom what I understand, you will need to deal with 'tuning' afterwards with the PSI or another computer besides GMPP. I was told the PSI computer would get me running but then I would still have to find a tuner and get it dialed in. I chose the GMPP parts so I didn't have to deal with that.
Realistically, if you tell PSI what crate motor your buying I can't image they don't have a tune for it that's right on. GM is selling a ton of these engines and if you leave it alone they should have pirated GM's tune by now.
I spoke to the guy a PSI a few times, he's very helpful and knows his stuff. Best bet would be to call.
Spankys Rod shop does a cruise control that should work with the GMPP harness.
