Strange thing! I noticed the last two time driving the car, it seems to have lost about 75-100 HP. The car idles and runs perfect, but the power is way off. I would expect the car to run badly and have a miss. It feels like the supercharger belt is off, but its making good boost.

 

Will answer my own question. I have been driving between Idaho and Washington and notice with the temp over 80 and a hot engine the power is down. I tried earlier with a cold engine and cooler temps and it is has the normal power. Racing it at the track I push the car thru the line and only fire it up before the burn out. That really helps my times Car has sat mostly for the last two years, so figuring this stuff out all over again.
