Hi all, took my SRT6 out today and had an opportunity to put my foot down and give it some serious acceleration whilst pulling on to a major A road but once I hit around 5000 rpm the car just stayed there, it would not accelerate above nor change gear, after being overtaken by the line of family hatchbacks I lifted my foot, the car changed gear and away I went again. I have tested this several times now and the car seems sluggish and wont accelerate above around 5000 rpm, just sits there. The car has had some work completed recently including a full service, fuel filter change, supercharger oil change, coolant, water pump and thermostat replacement, serpentine belt replacement along with other non-engine related items. Searching the forums there doesn't seem to be a topic related, perhaps fuel pump or air in intercooler circuit?

 

Video One

Shows foot to the floor and the car will not accelerate above 5000rpm nor change gear in automatic mode until I release the pedal, in manual mode it does the same thing no matter how many times a touch the gear lever to change.

Video Two

Shows than when I don't floor it in first it changes gear but once again with my foot to the floor in second gear it will not change nor accelerate .


I do have a speed sensor showing a value when the car is idle.
