The big head was just installed and I can pull 23 PSI towing. My question is would setting the big head up a little higher help low end torque or mileage. Normal highway speeds of 70 MPH pull about 3 psi of boost, where before the tranny service and big head the truck was pulling 5 PSI.
would there be any improvement in bottom end torque or mileage by setting up the big head a little higher. low end response and mid range towing was the reason for the big head. I do notice the turbo spools a lot faster at midrange but I have seen no response or slightly slower response off the line
Second, is the setting difficult to do or should I take the truck back to the perf shop where i had it installed.
Second, can anyone reccomend some cost effective tranny upgrades to increase tranny torque handling slightly.
thanks
