what a difference
between my stock 265's and my 315's with engine speed. . .before at this RPM I'd be doing maybe 65-68 mph, now I'm doing 75
pic taken with phone so it may not be all that clear. also the speed has been verified by two different GPS units[8D]

I'm running the 170hp tune on my smarty. . .yea, I can climb a hill
may have to try stock and see what happens. if I did my math right, my 4.10's running a 34" tall tire is the same final drive ratio of a truck with 3.73's running 31's.
