Re: Piggyback's
the "powermod" looks to be a crude carbon copy of the AEM FI/C. My concern now after poking aorund on Dealer Connect is our Crank sensor is a 2 wire and not a HAL/MAG sensor. I don't believe the AEM FIC will operate with that sensor, but I'll look into it a bit more. but as I was getting at earlier the AEM FI/C would be a true 100% standalone piggy back with full fuel/timing control independent of eachother.
Where as a simple Air Fuel Controller I believe will offer the majority of the features and I'm almost positive will work flawlesly. Only problem is timing/fuel are not adjusted independently. but that can be worrked around and again would be great to stack on a Canned Tune.
I'm going to start with the simple map clamp though I think on a stock SRT-6 it should be worth substantial power on it's own. I got a friend getting one to me as we speak. As far as wiring it's simply power, ground and splicing the 1 MAP sensor wire. Super simple and effective. lean the car back out and add a few degres timing. I'll be conservative and say 15hp stock.
