To be honest that was the deciding factor for me when I decided to buy Tuning software, cause everything else is pretty much the same...

Oh, last night drive I had the headlights, fogs, AC, radio, everything I could think of and the lights did not dim at all when the AC or fans cycled. And that is with the stock 105amp alternator...

Actually I thought about it, but I don't think so, my metal brake and bead roller have a hard time working with 18 gauge sheetmetal (which is what I used) if I upgrade my metal brake I might consider doing it. If people were local I don't think I would mind....

Can you tell me what the stock on/off pressures are and the on/off speeds?

I can find out after work, I have a 05 and 06 stock tune at home I can pull the number out of. I think the numbers are pretty close except the #2 AC pressure I lowered that way the AC would be colder all the time.

Here you go stock 05 efan settings. Remember these values are in PSI, not kPA.



The reason I changed the stock AC enable and disable was because the AC pressure usually sits 250-275, lowering the second fan value allows the fans to stay on full and provides the coldest AC when parked. That was after logging in 100* heat yesterday.
