Looking for info about my hemi, las couple years it seems like it's lagging power on takeoff . With 390 hp it should peel rubber a little but my truck won't. It's a regular cab short box, any help would be appreciated !

 

Moving to fourth gen for you.

 

With traction control it won't "peel rubber" and will apply the brakes until you get enough traction to hook up.

 

How many miles on it? When was the last time you changed the spark plugs and air filter? Have you ever cleaned the throttle body?

 

64000kms, changed air filter a month ago, never did change spark plugs ! All work would have to be done bu dealership due to still being under warranty. They did put it on their scanner and nothing came up for faults on timing or miss firing. As far as cleaning throttle body , no i didn't!

 

Comment about traction control , there's a button one can push to shut it off. Still doesn't peel rubber !!

 

It doesn't shut completely off. In a 2wd truck it is pretty close to off when you press it, in a 4wd truck not so much. Read your manual for details.
