I have a 2010 SE, with a mopar cold air intake and a Flowmaster one into two exhaust, and the exhaust sounds awesome, but I am not crazy about the throttle response that I am getting, is anyone else not happy with the throttle response they are getting from their car. I will punch it and it will take a second or two for it to respond. Would a predator make a difference, I am looking for quicker response and firmer transmission shifts, any input would be appreciated. Thanks!

 

I fixed mine with a ported throttlebody, there really is no horsepower gain, but the response is pretty good. I think it made a difference. pm me you r email info and I can put you in touch with the guy who does them.

as for firmer trans shifts, I'm also looking after that right now, I've ordered blue top solenoids from a member and will post my fidings. I have an SE (SXT) and yes there are limitations hindering it's true performance. the predator for the 2010 programming will not adjust shift firmness. This I know first hand, but I will be posting about the solenoids when I get them.

 

Did you try this?


PCM Zero/Span Throttle Calibration

Throttle calibration can substantially improve throttle responsiveness over "factory standard."

Many people notice what appears to be sluggish throttle response or a "dead area" at initial accelerator depression.

Throttle calibration can take care of these issues.

Procedure steps:

1) Insert ignition key and turn to "ON" (not start).
2) Wait for all idiot lights to go out. Check Engine Light may remain on.
3) Slowly depress the accelerator pedal all the way to the floor.
4) Slowly release the accelerator pedal until it's all the way back up.
5) Turn the ignition key to "OFF".
6) Start the engine.

Most drivers notice an immediate change in throttle response, but depending
on your driving style, you may need to repeat this procedure periodically due to
the computer's adaptive programming.

You likely need to repeat this procedure any time the battery is disconnected.
