off idle hesitation?

[bad monkeys]

I used to own a 2000 GT, but have since up graded to a 2007. My question is, is there anyway to get rid of the hesitation which takes place from idle to about 2200 rpm? The 3V motor would be a complete work of art if not for this problem. Any help would be greatly appreciated.

A tune will help, I've heard that CMCV deletes help.

get a tune!

Might as well get an intake when you get your tune. Doug from Bamachips and Brent from brenspeed are GREAT tuners and can give you a good deal on an intake/tuner combo. I went with the JLT Intake and SCT Tuner from Brent and the throttle response is greatly improved and the power is awesome! The price was right too (only $554)!

James,

You have an AOD or is it the DBW that was giving you heck?

The car is an 07 GT with a 5spd. The axle ratio says CG which I think is a 3.31 (correct me if I'm wrong). It's a great car but the throttle lag is a big PITA, especially in traffic. Any suggestions would be greatly appreciated. Thanks

I have an 07 GT also. Mine is a 5 speed Manual. I went with Brenspeed.com and bought my SCT Xcal2 tuner and C&L CAI with Pypes stainless steel mufflers at one time. It will make you crazy with the new power and NO LAG any more. Gas mileage will go up as a big plus, but you wont believe the second you blip the throttle the first time.

It turns it into another new car to re learn to drive and enjoy more.

I was at a dead stop today, light went green and my car nosedived like never before. I had just come off a 60 MPH drive with cruise on for say about an hour. I was like WTF? And never done it again all day Sunday.

Ya mines done that but not sure how ford will react to my warrenty I'm sure they'll notice my heads and cams. Might as well step up to the better fuel pump.

CAI + U/D pulleys + tune. So long to throttle lag.

 

[bad monkeys]

If the aftermarket can tune out the throttle lag why can't Ford do it? I guess this is what happens when you loose a couple of billion dollars in one quarter. Call it corner cutting 101...I guess.

Thanks for the information. Who has the better tune...Brenspeed or Bamachip?

 

[srothfuss]

From what I have read, the engineers at Ford detuned the factory setting to appeal to a much broader range of drivers than those of us who prefer instant reponse?

Bit it's just what I read....

Ford wants to minimize the amount of warranty work performed on damaged drivetrain components.

 

[rdmorrow]

Of the two, my vote would be Brenspeed.
I took mine to a mustang performance shop and put it on the dyno. They tuned it using an XCal.

300 hp sounds good, but they want to minimize the amount of abuse they will have to warranty. if they add lag, then its harder to beat on your car.

James,

You have an AOD or is it the DBW that was giving you heck?

~J~

Whats AOD and DBW stand for?
If you were talking to me, I had a bad throttle position sensor. It was replaced under warrany and havnt had any problems since!
