Weird little issue with 310??

[Klutch]

I have a little issue at idle with the 310/tcm tune. At idle with the a/c on, shortly after the a/c pump kicks in there is a hiccup at idle, like the timing gets jacked for a split second or the rpm's kick up for a split second. It doesn't do it in the ordinary 310 tune or even in the 275/tcm tune and it doesn't do it with the a/c off, wth? Anyone else experience this, thanks, Cole.

I haven't seen that issue and I have well over 1,000 miles on the production file for the TCM

I see that with the 275 v3...

Hey sask08, did they ever figure out what caused it?

No, just assumed it was the tune trying to adjust for the extra load of the A/C like the old carburated engines did. Thought maybe it was more noticeble because of the aggressive fueling nature of the tune.
