Highest MAP on N/A car
zip the file and post it... when you do a log it gets saved with the map your running. so just zip it and post it and when i load it up i will be able to see what you are seeing.
There just may be some spots where you have it to lean and your getting an increase due to the heat or detonation that is coming out of the valve seals.
do you have a wideband to tune the AFR's?

FWIW its probably a spike like Boe mentioned, and your logs will verify it. But the foglite pocket is the best location for it, it is a high pressure area and will definitely draw cool air under very slight pressure.
Allright... here it is... It's not 0.2 as I thought, but it's still showing positive pressure (0.1) For those with the R4 Controller, this zip file contains my modify version of the map. If you use it, you use it at your own risk. The recording to look at is the #3. Positive pressure can be seen at the very beginning of the recording.
The recording starts at 2400rpm and the manifold pressure is already at 0.1.

After looking at it... i don't see any real big deal. A positive number like that doesn't seem to be anything more than maybe a slight pressure spike from gas being stepped on or a possibly glitch when the recording starts.
As you look at the pulls with increasing rpm you are never able to get positive pressure... as you shift and keep pulling the pressure still never gets positive.
There's is either a possible glitch at the recording start point or a possible spike from the initial throttle load.
I can't see anything to prove a positive pressure from some sort of ram air. If that was the case you'd likely see it more often than what you do in the recording. I would disregard.
