I got my mack plug

Boost leak? You had the intake off messing with the pump so.......
 
775 running around town at crusing speed 65 it's about 625 or a little higher i could'nt find any leaks
 
That really doesn't tell us anything, We need to know what the temps are under max throttle(and what they were before).
 
I finally got the truck to run rite my problem was my linkage, the front part was so lose that it barely stayed
