I was wondering if there is help for me out here? I have a 95 with 370 injectors, hx40 turbo, no fule plate, shift kit, waste gate blocked and a set of 3500-4000 gov springs! I cant get my rpms over 3200 in drive! It will hit 3500 when im not in gear but it spits and sputters bad after about 3000rpm and pour's out white smoke! I have played with the springs and it make's no diff.... What could the problem be?

 

You need to time you engine to 16. Your truck is not fueling up to 3500 it will rev there but not with fuel. get you engine timed and everything will be good. &lt;---Piers said that<br>DM01

 

No fuel plate = no good. Grind your old one down to the equivelant of a 0 plate, but dont run without one.

 

The timeing has been done and set to 16! I had to have that done becouse I dont have the tools... What is the bad thing about not having a plate? And how do I know how to grind it?

 

I bet you guys will remember this thread <br>I think this explains why you dont want to run without a plate.<br>Get a BIG cup of coffee and read away!<br>http://www.turbodieselregister.com/f...p;pagenumber=1

 

Nope, but I seen you were running without a plate, figured I would give you a word of caution before you done extensive damage to the pump.

 

Thanks for your input! I have ground my stock plate and put it back in and it still runs the same! I dont realy want to spend hundreds to have a shop look at it! What is the chance of it being my delivory valve's in the injector pump or my supply pump?
