Pulls were in 85degree weather and 24% humidity


I must say these newer Dodge rams are hard to dyno espically if you have a Torque Converter...I wanna say I probably went through close to 15 pulls because even on the stock tune it just wanted to pull pretty funny on the top end maybe because it was just on the rollers vs the street. After talking to HemiFever (Sean) he told me something about a short runner valve that opens on the top end that usually makes late model dodges hard to dyno.... He might need to chime in to explain it a little more. I do have a couple of vids but I'm sure I those wont go up until tomorrow (gotta go to work tonight). Next up will be some track time's (maybe in 2 weeks) on these 22" wheels....depending on what I run/traction I might just buy some 17s or 18s with DRs for the rear.

GREAT INFO!!! I wish every thread was this good.
back to back dyno results with all of the details...

rep points for sure.
