Car has been running real good, very pleased with everything 
Yesterday, just for ****s and giggles, I decided to log a 3rd/4th gear run while merging onto a local expressway. Basically started at about 3Krpms and no boost and brought it up to about 5800rpms with 9 psi of boost. Car ran fine but I felt a very, very minor stumble. During the run I had to ease off the gas and reapply to get around a 'slowpoke' in my way
When I looked at the log after the run was complete I noticed something that looked a little peculiar. There were 2 spikes in the INJ D/C % graph line. Looking through the log I found that the first occured in 3rd gear at about 5200 rpms. At 5000 rpms my D/C was 65%, but then jumped to 117% at just 5200 rpms, the engine was not a WOT either, the TPS reading was 52%.
The second spike occured in 4th gear at only 4800 rpms, approximtely the same TPS % and jumped from 62% to 110%. Both times after the spike the D/C came back to a normal level like high 60's% and continued normal to the end.
What the heck is goin on? Hopefully I haven't left out any other important info. Both times the car was in boost, but not anywhere near wide open throttle. A/F ratio didn't seem to be affected, at least not that I could see.
