TPS Problem in MS

I have a E30 3.5l turbo. A beast of a car the name is "Loose". The car is megasquirted with MS1 029y4 does a great idle. Revs like a bear. There is a small problem I cannot get the TPS to stay calibrated. I can get it to zero as I hit the gas it starts to ramp up and the numbers from the tps start to climb like they are suppose to. Here is the funny part, the numbers zeroo for a second or two the car bogs. Then just like magic it purks back up and almost burns the tires of the rims. I was thinking maybe a bad e36tps so I changed for one of those automatic 6 pot jobbies and that suck even worse. Here lies a question is the megasquirt that smart to know when your car is getting low on fuel. Because usually when the fuel level light comes on the problems start. Or is it that the pressure in the tank is getting low and making it run like crap. :evil:

Does anybody know if Megatunix is self tuning? I forgot something
I could not get the TPS calibration working in megatunix. There is no such thing as automatic calibration. So I opened up megatune calibrated the E36 jobby and it was little okay. So what I think I am going to do is make a dual pigtail with both plugs. Use megatune to calibrate and see how far they are off from each other. What is the normal variance?

Thanks for the help I figured it out Megatunix you cannot calibrate the TPS MS1 Variants. Of course that is what I am using.
