Thanks guys. I figured those wx conditions would have an adverse affect on performance, just didn't expect it to be that much. Since the humidty was up and temp was down I thought it might all equal out. When Iwas getting 9200 with the 80s it was hot (near 100F) but, much lower humidity.
Then again, it might be my cheap tach not readying accurately. Even if it's not accurate it's still helpful in showing an increase or decrease in rpm. I've decided to buy a better tach. On the other hand, there was a noticable decrease in performance in flight.
Speaking of props. I've been wanting to try a 13x6 to test the difference in performance against the 14x6. Wouldn't you know that Ijust ordered more 14x6 props (duh). I'll have to make a trip to the LHSand pick up a couple of 13x6 props.

I'll be tuning on the 80GK again today because Iknow it's not right. It seems that as Iapproach best LS idle the transition sucks and it will die. Can't seem to peak the top end properly due that problem. It seems to run fine with the low end tuned rich but, it's not at optimum idle. Ithink I'll change plugs to see if it helps.
