Very Slow 08 Please Help

[SRT BEE]

I had not driven my car for about 6 months until this week and it is a real dog! It will not even brake the tires loose in first gear, it is slow to raise the rpms, and it lacks pull even when over 4500 rpm. What gives? My Cummins pulls harder than this I'm not kidding.
Last year it would get sideways in second gear and pulled hard at any rpm. I had my Body Control Module (BCM) changed at the end of last year under a recall could this have something to do with it? Does something need to be reprogrammed or flashed? Or has something else gone wrong?
Before you ask the gas is fresh.

Mark it has not had a check engine light

If the dealer flashed anything they could have messed it up and changed the throttle calibration or forgot to. Definitely take it in and have the thing checked out. No check engine light means it does not see a problem so I would lean to wards a calibration problem from the swap.

Let us know what you find.

Put 100 octane that's what I do and never have a problem putting my car down 6 months at a time.

How do they do the calibration?

How do they do the calibration?

They will hook up a STAR scan and link the PCM to the Chrysler site. Then they will prompt for the calibration sequence and the Tech will need to follow all the instructions to a tee. There is always the chance with a wireless connection of a faulty calibration. They may just have to do it again, if that does not fix it you could have a faulty pedal sensor? The dealer will have to dig for embedded codes stored in the PCM and clear all of them before the calibration also.

Any octane should be fine for at least 6 months.

I was in Spain for 14 months and left all my cars with a tank full of 100 came home and each started without issue after a new battery.
