Formula for Boost changes?
Are there any tricks or formulas to measure BOOST via Data-logging?
I know Atap has MAP pressure , engine load and a few other sensors but not sure how to use those to see boost level or changes.. Any ideas?

Using the above formula on my new ATAP update (version 3.2); I am seeing 60.9 in.hg@ 6200 rpm on todays runs. That translates to 15.25 lbs of boost? This is with a pulley and 80mm TB only. ATAP shows no signs of dumping boost or fuel yet..
It was 87 deg ambient and new I/C pump was working great! Full tank of gas and with a passenger, still spun tires hard from 28 mph punch and spun tires on second gear shift for the first time.. The 80mm TB really helped the pulley out!
It took 4 WOT throttle runs for the car to learn and settle in..
PS, the 3.2 version from ATAP really updates a lot quicker!
