(I'm new to this),,I bought a 95 2500 12v with 242xxx auto,brand new 4" exhaust also the kid before me took the fuel plate out and turned the star wheel all the way towards the front of the truck, he bypassed the stock lift pump(from what I know) and put a gold flo electronic fuel pump on, there's a pump in the tank too,I'm not asking for smoke, doesn't really matter to me, but with out a fuel plate and the star wheel turned wouldnt it smoke a bit? Also just changed fuel filter,just doesn't make sence to me

When i first bought my truck that is how it was setup, pre boost was never touched. It didn't really smoke at all either. Now throw in a GSK and it will black out an intersection... I ended up grinding a plate and tightening star wheel after GSK. Not a smoke fan, its just $4 a gallon wasted fuel.

I got brand new 4k gov springs for it, just haven't put em in, when I first start it it'll puff alittle but once the truck warms up alittle there's nothin,

If you screw in pre-boost it will smoke, but no as it is tuned it is not abnormal to not see much smoke. It means the turbo is able to keep up with your fueling and is not a bad thing. Unless she doesn't seem as fast as such a tune should be then you may have a lack of fueling/fuel pressure problem.

Also dont even think about installing those 4k's before doing valve springs... or you can do what i did, leave inner most spring out and its now a 3k kit and safe (more or less) without springs.

Where's the pre boost screw? Sorry this is my first cummins lol

Not sure how you did that but cracked me up haha ^^^^

 

[alextsi66]

when I had no plate and star wheel turned I could smoke like crazy! not sure why you cant... fss not open all the way, ofv not working right, low fuel pressure, injector issue?

 

[Gisondi14]

It makes no sense to me,, with 2 fuel pumps it shouldn't have low pressure, it doesn't blow white smoke so shouldn't be injectors, idk

I had two lift pumps and still had 3 psi fuel pressure, granted there was no spring in the OFV at the time.

Either way, these engines like a higher fuel pressure then your normal electric fuel pump puts out, I would recomend atleast checking the OFV and possible getting a fuel pressure gauge. http://www.cumminsforum.com/forum/94-98-engine/137589-how-check-fuel-pressure-12-valve.html

There are a lot of people that inaccurately call different mods 'investments', a fuel pressure gauge is an investment.

 

[Warferox-Veritas]

An electric fuel pump on a 12v is NOT an investment...

Hm alright, thanks
