The hell just happened, losing to a 14' challenger rt

Did a 40 mph pull with a friend who owns a stock 14' challenger rt (372hp/400tq). When i floored the gas the car hesitated for a good second or two before taking off, while rt was almost instant when floored leaving me a car length behind the rt. Im still on stock tune and been driving slow lately due to traffic. Im not sure if its the adaptive learning thats confused when i floored it because im pretty **** sure my car suppose to be the faster one lol. Ima get my rematch soon.

A tune seems to shorten the throttle lag quite a bit.

All joking aside a throttle relearn can fix that a lot as well.
It can make a big difference.
But yes a tune will really fix it!

If it was from a 40 roll like you said you should have used the Select Shift to lock the trans in 2nd. Punch the gas on the hit and the car will pull instantly like a manual without having to wait/hesitate do downshift and then start pulling. This is where the Select Shift shines. Then a moment before you reach redline in 2nd, just bump the shifter forward into D and let the auto trans take over.

If the GT is like the V6. Pop the hood and look over to your left (passenger side). Open the long fuse box. Pull fuse number 47 and keep it out for an hour or two. This resets the adaptive learning. I do mine once a month to keep things fresh

What kind of racetrack were you at that you got to drag from a 40 mph roll?

Probably on a back country road in Mexico. I hear the cartels use a lot of R/T's down there.

Are you sure it was a 5.7?

Are you sure it was stock?

Are you sure this person was actually your friend?

Are you sure you didn't just dream this scenario?

As cool as they are, there's no way a stock 5.7L Challenger R/T should be able to keep up with a Coyote Mustang...but as folks mentioned, relying on the down-shift logic in auto mode where the Challenger driver knew what he/she was doing could easily explain a loss like this.

I always make sure to have some spirited acceleration every day so that the adaptive learning doesn't go all soft on me.

With Select Shift there's no reason to be in the wrong gear.
