White smoke?

[CRASHJT]

Just picked up a 96 f-350 dually pretty stock only known mod is fuel reg. shim (aka BB behind spring) I notice that when free rev'd the engine revs farely good till about 2k to 2300 then it kinda chokes up a bit and will rev kinda sluggish past that (kinda thought that it was due to the stock crap down pipe??) but then will blow some white smoke clears up as soon as you let out of it. any ideas?? and help is greatly appreciated!

sounds like you have an injector on its way out. how many miles???

211,??? thats gonna hurt....lol mainly because you know I cant go to stock...lol curious though will injecters out of a superduty fit and if so would it be any kind of an upgrade?

I have the same problem, not to thread jack but mine will pour white smoke but i buzz tested the injectors and did a contribution test and it all came back good......

if you compression is good...

then start with the smple stuff. BB mod should be fine for you, but if your goign to mod anyway, do all the simple stuff first. DP, Intake, maintenance, etc. but as i said, be sure your compression is good. get your cct and injectors buzzed. could also be just soem injector o-rings too.

Anyone on the superduty injectors? a friend of mine has tons of them so I could get them for free or dirt cheap?

[kanuck15]

They are bigger but you would need to reprogram your PCM and get a better HPOP to run them. its really not worth it

[CRASHJT]

Im only arguing the worth because I could probably get most of the stuff for free minus the PCM tune which I want a chip anyway so??? If I could get the superduty HPOP and a set of injectors for free the have a custom tune made..... Still not worth doing? Thanks for all your help!

if that is indeed the problem, then yeah id say imho its worth it.
