I was wondering if anyone has had the same problem as me, When I jump on the throttle and my trruck shifts at 5600rpm into the next gear, I hear a loud popping noise, It only does this at WOT and 5600rpm?

5.7 hemi, auto trans.

I guess I'll see what the dealer says about the noise, I'm gonna test out the "Lifetime Warranty"

 

IDK if I would tell them it was at 5600 rpm. They might not like that.

 

5600 is a stock rpm they shouldn't oblige really just say when you throw the coals on it does it and judging by some other hemi owners and my self my truck does it too. My theory is that it is the TMR pulling timing on the upshift to kill power essentially making a small backfire.

 

I've raised my shift points to 6k with my tuner. Only thing i get is a major lag when shifting and she rockets into gear. Only noise is from my neck bone getting displaced....lol
