this is how it does it now...
2nd-3rd shift @ 6000rpm = 3705 rpm in third

shifts changed would be
2nd-3rd shift @ 6500rpm = 4010

this is 305 rpm difference and 8mph later. my best trap speed is 89

also what is the official story on the pcv valve... makes a difference or not? seems to be a little dispute in posts there. also, IMO the SOTP meter tells me this truck keeps pulling after 6K, at least in first... might be different after the trans ratio changes. i dunno.

I am a bolt on 5.3 as of right now and i trapped my best at a 14.8x at 94mph.
I also ahve better shift extension that that however.I shift from 1-2 at 6000rpms=45mph i shift from 2-3 at 6100rpms=90mph
If you raise your rpm band to 6500 on the 2-3 you should get out of that dead zone your hitting right now as well as be at a better mph in general.
ECSB's need to turn a few extra rpms we just weight too much to turn the same as a reg cab and expect the same results.

something might be wrong with your converter dakota. i'm running the same one but the heavy duty version, with 4.10's. my shifts are set @ 6400 and my shift extensions falls down to 5k.

well, foot on the brake sittin still, it'll flash at about 28-2900. then the tire/brakes let loose. normal driving...75% wot and less, it will jump to about 3300 and let the mph catch up and then climb with each other. 75% or more it will jump to about 3700 and speedo catches up. so i wouldnt "THINK" anything is wrong with it, it doesnt give me any lip normal driving. no surging/chattering/excessive slipping (3700+) but my gas mileage has completely **** on me the last few months, coincidentaly about the time i plugged that damn hose back on is when it started
