Nice! They seem consistent lol I run a 305/40/18 DR which did OK...now I am going to run 325/45/17 M&H soon to help on the street.Looks good!!! Congrats I have your same set up made 650whp with Lund tune also. What size drag radials are you running?
Thanks! It gets violent around 6000 rpm though lol but usually it'll hold the power. This was at Brother's Performance.Very nice TQ curve to get traction. Which shop was that?
What was the peak boost?Just the new pulley but everything else is the same. I would say it was making 620/500 with the 3.8
