The he pump? Not sure. I know the shop had to add some coolant to it or whatever fluid is used. Could this be the issue? Its a shuddering feeling as the car goes WOT.

No cels as of yet either. If the iat's were high, wouldn't the supercharger just not engage and the car wouldn't hesitate?

one car at a time
I tried to purchase a live scanning tool today that has playback but they were sold out so I'm going to have to wait until Monday and run the car by benzworks in huntington beach for them to diagnose. I also got word back from adam at EC and he recommended a re-flash so depending what we find on Monday, I will reflash possibly. Hoping it is something simple like the belt slipping

I might take you up on that, thanks. Yeah, I've heard that too. I would be fairly pissed if that's the case, but would high iat's cause my symptoms, or would the supercharger just not engage and I would be low on power? The hesitation feels like timing is being pulled more than anything else.

This issue is common on stage 3+ cars when going full wot on the streets from 3rd to 4th in s mode
Only fix I have seen so far to go wot with out the hesitation is to use M mode
IF you do find a fix do let me know
from what i recall it was something related to torq limiters, but that was just a statement

Well, I don't want to say for sure quite yet, but the problem seems to have solved itself. I'm going to go out a little later and try a 4th gear pull to be sure, but 2nd and 3rd felt great with no issues a few minutes ago.
