got an 07 lbz with edge attitude and juice 5 inch mbrp otherwise stock its been overspooling (35-38 psi) under wot with power loss on anything over mileage tune if i back out of throttle and get back in it itll accelerate again just wondering if a ported fitting or maybe shim kit for fuel rail would help or should i go ahead and get a lift pump like fass or air dog. This is my first diesel kinda clueless anybody got a solution?

If it were mine I would go ahead and get a pump and shim kit.

thats alot of boost... You shouldnt need a pump with the juice/attitude, so try the shim kit before you drop some coin on a lift pump.

I dont know why your truck would be boosting that much... Mine maxes out at about 26psi with the juice/attitude and I've never gotten a code due to low rail press. Hopefully someone who's much smarter than me will chime in about your boost issues...

Edge equals automatic shim kit. they will always throw the truck into limp without it
