Anyone know what the differences are?


I've tried my buddy's 4.61 unit before and bought this 3.2 unit for myself on the weekend assuming it was newer than this.


It doesn't seem to run quite as smooth as the 4.61, with the cruise control set it surges a little bit (maybe .5 of a mph) I can see the speedometer needle quivering a bit while driving down a slight descent on the highway.


It also seems to make more power than what I remembered the 4.61 making, but I could be wrong..


Anyone know what issues were addressed between version #'s?


I'm just curious, I'm trading it up for the 4.73/attitude anyways.Edited by: Camstyn

If you are running the 3.2 that is likely why your oil psi is dead...

WHAT?????

Juice 3.2 and older versions such as it make the oil pressure gauge settle on 0 on 03 and newer trucks. No big deal, oil pressure is there, just not showing on the gauge. Check my duramaximizer installation problems thread and John explained it well there.


PS, traded in the 3.2 for the 4.73/attitude today, it rocks! The 3.2 smoked a lot more on level 4, even with the low boost fueling turned up to 5 on the attitude. The 3.2 feels faster on level 4 than the new one does on level 4, maybe the new one's just smoother.


I like the new one, level 5 hauls ASS, smokes really good and is smooth as butter.
