I'd like to request a Custom 91 octane performance tune.

I have a 2005 Ford Mustang GT manual trans.
Details of my tuner device are in my signature.

The specific item I would like to have customized is my Dashpot setting. Reason is because my idle takes too long to drop between shifts.

I've already checked for vacuum leaks and cleaned the throttle body with no change to the slow rpm drop. It takes about 4-5 seconds for idle to drop from 3500 rpm to idle.

I recorded the slow dropping RPM's, click the image below to see it.

no CAI on the car?

post the current last tune written file please.

No cai installed, do I have to upload the actual tune I'm using or can I tell you which one I'm using?

If I can just say which one it is, it's the 91 octane Performance Tune for a Manual trans 05 GT. My predator model and version are listed in my signature.

no Cold Air Intake.

give this a shot

Thanks Mikel! I'll try it out tonite.

Could you tell me what setting the dashpot was set to and what it is set to now?

Well at a stand still, the RPMs come down quicker than before the custom tune but at speed, they come down slowly at the same rate as before and seem to drop as the vehicle speed drops. Any ideas why that would occur?

Is there a setting called "drift" that is adjustable? I read on Mustang forum that a member who had the exact same issue that I'm having, went to a Ford Tech and they a vaguely recall the Tech altered something called drift which cured the issue.

here you go. try that. let me know if this is good or if you need more aggressive or less.

Thanks Matt, I just confirmed that ill be picking up a JLT series 3 110mm CAI tonite, could you apply the Dashpot settings and settings for the JLT CAI into one tune?

here you go...

You guys are AWESOME!

Installed the JLT series 3 cai and tune, it's awesome but I need the idle to drop faster still. It's alittle better but it's still slow to drop.

Can you record a quick log with the default pids so Matt can check it out?

Thanks
