2011 Dodge Charger RT problems

Post by Playhard »

I'll post the same thing i posted to the contact us page. Having issues with stock shift points after install of the 91 and 93 tune. Throttle boost at 20%. Problem is that the car shifts way to early with moderate throttle. Shifting at 2100 rpms or less. At 30 mph its in 4th gear under moderate throttle. Stock tune shifts at 3k with same moderate throttle. I've tested this. What gives. lve also notice flat spot or lag at 1600 rpms. Also, Car will not downshift on uphill grades when accelerating like it does stock. I've tested this also. I like the extra power and notice it in WOT or autostick, but this tranny, shift stuff and bog/flat spots are driving me nuts. I'm afraid of frying my pcm with so many reinstalls. Very frustrated. HELP

I cant say I have seen anyone else with this issue, try pulling the pcm fuse for a minute to reset everything and see if that helps.

Pulled the battery cable this morning for two hours. Reconnected. Ran several test runs with stock tune and diablo tune. Same result. Very noticable.

I'm having nearly identical issues with my 2011 RT AWD.

So Mike, has the team cracked the code yet on shift point management for the dcx on 2011-2012 Charger RTs.
I think this would solve the issue of shifting to quickly. I did back down the throttle boost to 10%. Did not notice a huge difference in shift points but agree this probably has something to do with it. Any word when if ever we can expect shift point managment?
