He want not on a dyno was he? [8D]

 

sounds like dyno runs to me. . .but then again Ty has the program to do 4K. . . .

if you want to be able to do that, invest in new springs, turbo, and fuel. I'm pretty sure the stock injecctors can keep up with 4K.

 

I'm curious, the speedo goes to about 85 on there but I've pulled my 9K trailer on the freeway at 85(once)and never came close to 4000 RPM. Is dynoing that hard on a truck? I'venever done a dyno so I'm just asking questions, not bashing or anything.

 

I was thinking he was in third gear or had a hell of a low rear end

 

nope. . 48RE, 1:1(3rd gear) and 3.73's. . .that'll get you that speed.
