Everything seemed normal. I was boosting about 38 MAP at 4500 rpm and 5000'. I was gently adding a little throttle to increase speed for another ASI calibration when I felt a surge of acceleration way beyond what I'd expect for the minor throttle adjustment I'd made. This was literally a shove in the back. It lasted maybe 2 seconds, then the engine carried on at the new power level. RPM jumped up a couple of hundred. I glanced down at the MAP. It had dropped to 34. My best guess is that I'd been running with a gummed up plug which suddenly cleared and gave me added power. I'd appreciate any opinions on this. Now if I could just make it happen again - and again.....
