turbo guys, are you boosting with 3.42's at highway speeds?
Evening gents,
I'm bringing my truck to get the rear end rebuilt and an eaton installed this week and I want to go drop down to 3.42s from my 3.73s because a turbo is in the new future. I know its dependent on the turbo characteristics, but in general, are you making boost with 3.42s at highway speeds? I have a rcsb 4.8l 2wd. THANKS

right, i guess i didnt word my question properly. I just meant when you're cruising at highway speeds and only at partial throttle doing a constant 75 mph in over drive, for example. I didn't know if the load on the engine at those higher constant speeds typically produces no boost, 1 psi, 5 psi, etc. Just curious if its gonna be eatin gas with 3.42s at constant highway speeds. Its my first turbo build so i'm not really sure what expect. (PS: I hate bein a newb)
