6.0 Stalls when depressing clutch pedal if AC is on
This is probably the last thing I have to figure out and the search button didn't get me the answer. My tuner claims he can change the engine decel speed to avoid this but I want to know if there is a more direct way.
She runs great and never stalls ever when clutching as long as the AC is off.
When I switch on the AC, my fans draw full current and the extra load causes an occasional stall when I depress the clutch. Gets scary trying to turn through an intersection and I lose steering and brakes with 38" tires mid-turn. Is it as simple as connecting something in the AC system to the AC request line on the PCM? Has anyone done this? I have no problems idling in a parking lot as the engine always catches the drop in RPM and adjusts accordingly. Its when I'm physically driving that the issue occurs.

Fixing it in the tun is probably the simplest and best way.

We did adjust for it in the tune. At this point it seems to be ok. Still logging some miles to see how it holds up. The downside is that the idle speed was raised to 1000. I believe he added some timing which pretty much makes the 1000RPM like a brick wall. I'm just not used to the slightly higher idle though.

you should be able to find a happy medium. You're not cammed are you?

Stock for now. Just got my wideband installed. Hoping to dial things in a little bit more. I have decel pop every time I clutch and the wideband is confirming a rather rich condition when I come off the gas. Ran the ac while driving out on the beach for a good hour yesterday. Never stalled so that's good.
