I'm running the P3 in Tucson, Arizona with temps coming in 180-190 and the motor is so well rounded from bottom to top end it makes a truggy (X2 CRT) very hard to beat..

"I didn't see this addressed in here yet, I know a few people that have like a gallon to a gallon and a half of fuel threw they're .21 tuned GRP's and have no pinch to speak of, they still seem to run decent but hardly any pinch. I've got not quite a gallon on mine and it seems to be loosing it also, has anyone else experienced this??"

Is the engine still idling? Whenever I saw motors lose pinch I also saw the idles consistency turn for the worse.
