Default Is this throttle lag?

If I step on the gas 3/4 to full from idle roll or 1/4 throttle I get a big buildup of RPM's then the car finally decides to respond and will begin to speed up. I can hear the engine build up, but the transition to the wheels is majorly delayed (a couple seconds.)
I have a C&L with 91 Bama Race tune, GT500 take-off.
Any suggestions.

Auto I assume? Could be something with the trans not down shifting properly, What happens if you put it back to the stock tune?

I agree that sounds like a transmission issue

I remember this doing it with the stock tune also. And actualy I didn't meant to put 1-2 sec. it seems that long but probably just .5-1 sec.

I have an auto and the shift from 1st to 2nd can have some hesitation, but I don't think its a problem because my car is incredibly smooth when it shifts. (at least as good as the bmw I test drove before getting my mustang)

Its not a shifting issue. I can be in 3rd or 4th gear and just rolling and put full throttle and lots of engine rev but no go go for a couple moments.

I think it sounds like you are simply dropping down a gear. I know on my 2006 v6 auto, if I am driving at a constant speed and step on it, it does that. That is just the tranny dropping into a lower gear for more power.
The same thing happens on my chevy truck and my wife's dodge minivan.

This could be the case. So is there anything I can do about it, or do I just not know how to drive.


This is frustrating when another V6 that I know I am faster than comes by on his throttle and i'm just cruizing and try to step on it and.....and............. then I get acceleration.

As far as I know, that is just how autos downshift at large acceleration loads. Most auto vehicles are that way, maybe not quite to that degree, but that is how it is.

Did you ever take your car back to stock tune?
