I had the recall done on my Commander with the 4.7 (reprogram the engine so it doesn't stall) and I can't help but feel that it feels sluggish after the work was done, especially with the A/C on. I have about 68k on it now so I know its not a spring chicken anymore but still after the recall was performed climbing hills and all it feels like they took the fun out of it. Anyone else experience this? I do have the K&N FIPK system installed on it, when I mentioned to the service manager that the Jeep felt sluggish he of course blamed the K&N and said that the new programming would take time to "adjust" to the K&N and to just be patient, it has been about 2000 miles since the recall was done, he also suggested cleaning the K&N Filter which only has about 40k on it. Just wondering if i'm alone here or if anyone else who has had the recall done has felt the difference? I do notice that it idles much smoother than before and you feel a lot less vibrations and idle jump like before the reprogram.
