Any idea what the threaded port next to the inlet is for? I know some sort of solenoid or something is suppose to be there, cousins truck has it. I wanna know what it is/ does to see if I can get rid of it or unplug it.

Its a solenoid. It limits boost and give electronic control of the turbo some what at least. acts like a 2nd wastegate On stock trucks if your gona use the wastegate you have to keep it pluged in. Itll throw a code. But the regular wastegate will still work its like a hx35. on swaps they sell a plug to block it off. Im gona wire or weld the wastegate shut because with it clocked it doesnt line up and plug it

i was installing my ddp stage 3's yesterday so i decided to put in my longer fuel screw but seemed to bottom it out? did you have this problem? it still has lots of thread outside the pump so im confused. plus id thought i would be running more psi with those large injectors since im only hitting 25psi. i also did the bango bolts out to 3/16

Do you still have a stock lp? Larger injectors will suck it down to zero psi and limit power

O i thought it was a 91 non ic its a 93 sorry . and on tapatalk i cant see sigs. Did you bump the timing up? And where is your starwheel set that will influence it and mine still had a decent amount of thread out of the pump
