Default What Timing to Run

My 94 2500 has ddp 75hp injectors, afe stage 2, ddp #100 fuel plate, and a 4 inch turbo back exhaust. I was wondering what timing would work well with what I have done to the truck. I have a feeling it has slipped the truck runs shitty at lower rpm and fuel economy isnt the best. I just put a new lift pump in it so i know its not fueling problem. Ive got 263000 miles on the truck only had it for about 4000 of it . Any input is helpful.

16-17 degrees probably would be good.

x2 Prolly would hurt to check or replace your head bolts before you advance it. Or just put studs in it if you plan on more mods/HP.

Yes my statement was just what timing would be best not what would be best for the rest of the motor.

Unless they have been retorqued. A good flat head and tight bolts it will hold more if you ask me. Seen it more than once.
