A bit sluggish....

[Big Red902]

Hey guys, first post. Hope you cann help. not too sure whats going on with the truck right now, 2011 crew cab 5.7, its feeling a bit sluggish and slow to respond sometimes. Even after its heated up and been driving for a bit, also right around the 1800 to 2000 rpm range it feels like its.....down shifting but no flux in the rpm or spedometer. Its been a harsh winter up here in atlantic canada, but ive always taken the time to warm up the truck. Also, what are somethings to look for when either hub assembly or tie rod end starting to go......pot hole are unreal aswell. Thanks in advance guys.

Tie rods you need to move the wheel back while the truck is in the air to see it rocking. If its rocking it is bad, wheel bearings there would be a grinding noise and it would change when you turn left or right. I would try disconnecting the battery for an hour so the computer can do a relearn of your driving habits.

how many kms on it? Time for plugs?

Drive using tow/haul to disable the 'eco/MDS' system. I notice it on really cold mornings when it first kicks in, it's more of an annoyance until I drive the truck for a bit.

I hate to say it but as pleased as I am with the HEMI, I find it lacking below 2500rpm. Compared to my previous 2000 5.9L V8 Durango R/T which has instantaneous torque off the line. The Hemi is quick to get to 2500rpm at least with the high HP, but in winter weather I often accelerate around 2000rpm, making it seem like a lackluster engine until it rolls past 2500rpm.

Get a tuner, really woke my truck up

Only 46000km on it, plan on doing the plugs this spring. How much are tuners now? And hemifever or diablo?

I just picked up mine from Moe's, I went with the Diablo Intune and the HF custom tune that was included...here's the write up that I did:
