automatic overdrive (transmission) and drive by wire.

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.

Absolutely, its called torque management. Drivetrain lash is minimized too. I hated the slow throttle, tune fixed it!

It's possible that Ford tuned the cars with throttle lag for warranty/financial purposes, but what about all the other performance car makers? I have never heard that Chevy tunes their Z06 Corvette for reduced throttle response. Does anyone know of any other sports car with this factory setup? I makes me frustrated because producing a performance oriented, 300 hp sports car w/ throttle lag is oxymoronic.

Supposedly the DBW as opposed to cable is not the problem. I've heard that F-16's are wire throttles, and they don't seem to be unresponsive.

My problem with retuning is that it's been my experience that anytime you mess around with the onboard computer, all it causes is problems. I haven't really heard of too many with CAI/Tune but I'm sure someone out there has experienced problems (i.e. the inability to retrieve the factory tune for service/warranty work).

I am conflicted on this point because I want the increased performance, but don't want the risk involved. Some mods only introduce the need for more mods, and it becomes a neverending (and expensive) endeavor.

I have the X-Cal with a Brenspeed tune. The X-Cal tuner has space built into it for downloading & storing the factory tune. When you plug it into your car for the first time it will download the stock tune; you can't install any of the tunes in the X-Cal until you save the factory tune to it. I have reinstalled the factory tune each time before I take my car into the dealer for service or warranty work, and then reflashed it when I get the car back. It is foolproof.

I agree that it is a sad state of affairs when after spending a ton of $$ for what is supposed to be a performance car, we're forced to spend another $400 or so to correct a deficiency like throttle lag. I don't know if I necessarily buy the argument that it was engineered into the GT to keep people from tearing them up, as much as when it was discovered Ford didn't take the time & effort to engineer it out. The idea that Ford put the throttle lag in there so that the car would appeal to a wider customer base is rather hard to accept. It's a V-8 Mustang after all. The wider customer base is why there is a Mustang with a V-6.
