exhaust noise after tune

i put a s&b intake with a dpf/doc delete and a spartan with a 210 early lock tune. the cat back is stock with muffler and at the tail pipe it sounds like well,air rushing out of a 4 inch pipe, kinda like if there was avacuum running at the end of a 20 foot pipe? i'm writing it off as the stock twin tip with the holes in it.i have had similar with a truck with a clogged cat but way loader.

allso i'm assuming the early and late lock is reffering to the tranny? early for dd driving late for race?

Early is actually better for racing. Most like it all the time though. Late lock is more for the guys who don't like early lock and those with larger tires.

Im guessing early lock with larger tires (in my eyes 37"+) may bog the motor down?

not that i'm a diesel expert but my reasoning was the earlier the lock the less power you have,the later is higher in the rpm range,but when you have 1000 ft lbs of torque and such a low peak hp range does it even really matter??or would it be based on your turbos spooling quiker at the higher rpm??? that would give you more go off the line.

you answered my question with more questions My assumption would be that an earlier lock is better for your tranny if you are applying max power, so that your gears no longer slip and are firmly locked to Handel the power.....WOP throttle or pulling a heavy load without your TC lock up i think can pretty much chow your tranny....

when you have taller tires, you have a greater RPM drop on shifts. The later shift point means you don't pull down to as low an RPM so you don't experience lugging, excessive smoke, higher EGT, etc.
