Low ICP? and P1211 code

[soutthpaw]

I have set the P1211 3 times now running on the 100HP tune. they all came under hill climb at acceleration at a mile high or higher. showing 31-34 Manifold absolute pressure. not sure what Bill has the trigger points for the code set at but it was about 61-65inHg on my AE scan. Bill I am open to ideas if you have any... Just haven't got around to looking at the issue. Cleared the codes with AE.. problem solved

I actually missed seeing what my boost was but my gauge was showing above 20PSI when I glanced up at it...

EDIT: I just remembered i wrote down the DTC results from the last occurance on my BlackBerry but didnt put down the rpm throttle data etc as i was driving at the time
