I bought an elbow off of e-bay that was supposed to be set to "max" (around 35psi). My quad recon tells me i get no more than 25psi with a truck bed camper into a hellacious headwind. My egt's shoot up to 1250+. I have no problem maintaining 75mph on the hills that are I-25. Granted, my camper weighs very little, but the wind resistance was more than usual.
My question is this: what type of boost elbow are you using? and, will opening the exhaust to a 4" Jardine or maybe even 5" help the egt's that much? Will my e-brake make a difference?
Thanks for all the great info and advice so far guys... ... keep it rolling!!!
