05 Mustang GT

Cant wait for the fallout from this

Anyways, I installed my CAI and tune several weeks ago, huge improvement. Only issue I had was that the idle would now hunt from 600-800 rpm. Emailed Fred at EVO he stated its normal, OK no biggie. A few weeks goes by and the rpm no longer hunts, I guess a good thing but the car doesn't seem to respond as it did when I first installed the tune. I am just used to the new setup or does the tune need reflashing occasionally?
I did reflash the tune the other day and the rpm is now hunting 600-800 rpm at idle and car feels more responsive.
What gives?

Thanks, and I am ready for the fallout.

Maybe the ECU relearned.

that never happened with my brenspeed 91/jlt2 combo, it
was pure heaven

hope you get the issue resolved, so you can enjoy your
stang once more

i've seen, as i'm sure you have, where lots of folks "lose" their tune and have to "reload" it. don't know if it's true or if it's psychosomatic!

prolly already is, but make sure TCS is disabled, that makes a difference. also, turn ur idle up a bit, see if that does anything for ya. i have mine close to 1000, i like it there.
