Ok, so I asked this in the 6.4 thread and a few people responded but I have kind of further refined my issue.
Pretty much driving down any road if you floor it and let it downshift a few times and let off the throttle will stay wide open, it has progressively gotten worse to the point where this morning it held for a full 5 seconds and almost caused me to rear end someone merging onto the expressway.
The trick is air temperature, it had to be below about 35 degrees and the colder it was the worse it acted up.
After my almost accident I got out my tuner and went back to stock and on the rest of the way home it had zero issues, so my problem is with the tune (hemifever 87 tune).
Can anyone else simulate those conditions and see if it acts up? I am going to email Sean to see what the issue is, but I'm at a loss here. It didn't act up last year at all and suddenly this year when it gets cold I have a problem?
The easiest for me to replicate it is really anything above 50 mph, put it to the floor and let it downshift to 2nd or 3rd, in anything under 30 degrees it would stick every single time.
