Once you finally get your car to a tuner then it is probalby only 15 min away from running the way you want. Crazy that there are none in your area but I would not just go to the closest and available guy out there. The tuning is so vital to the safety of your engine and must be done by someone with a good rep. Even if it means you have to load it up and drive to get to one. It will be worth it and mean fewer problems down the road. I went thru two months while building mine so I totally know the frustration and brain thoughts you must be having. But it will be worth it.
Just waiting to find a tuner and get a trailer and truck. Gotta know where I"m taking it and when.

Is the check engine light working? With those 3 codes it should be on. It should also do a bulb check at first key on.
That MIL code means either there is a problem in the circuit to the MIL lamp, or an ECM problem.
If P0650 comes back after clearing, I think that's the key to whatever is wrong.
I'll clear it for now just for the hell of it.
I'm just in waiting mode now till a tuner can get ahold of it.
Anyone know where I can get one of these? I'll call Magnuson and order one but I was hoping to get one locally. Went to 2 different Orileis, an Auto Zone, Car Quest, Advanced auto, and and a couple others today. Nobody even knows what the hell I'm talking about.
