low icp with IDP extreme street tune? Normal with all others!

I just did an injector, and oil change in my truck. Fired it up, and was monitoring ICP (I always do after any oil system work). I noticed my ICP was very low-it peaks around 1700, but is usually around 1500. This is ONLY when I'm using my innovative extreme street tune. I run the stock tune, and I have 3500+. My dfuser extreme race tune is also 3500+.

I don't recall monitoring my ICP with the innovative tune prior, but she seems a bit down on power. Starts, runs great, no problems there. Fires right up even in 10 degree weather, no smoke or other noises. I'm kind of leaning towards a problem with the tune, as all the others have good ICP. Even if the Innovative tune was pulling too much ICP and sucking the pump dry, it seems as though the dfuser would be as well as both are similar power levels?

You guys with an insight and a IDP extreme street-what are you seeing for ICP? I think it's time to check my IPR duty cycle and see if I have any a weak pump

Amazing what a little searching will do for you. Apparantly it's normal. The IDP tune tells the ecm to multiply the actual icp reading by .5 in order to change pulsewidth. (at least as I understand it). Turns out it's perfectly normal.
