my mods are in my sig, and with what i have read i should smoke like a freight train. i dont want that but i need some smoke to tune from,the problem is i have no smoke at any rpm,and the truck still has stock power. i gutted the afc for a day and only got a good haze at wot.i cant yet check fp cause i am waiting on parts,but i have a new tork tek adj. ofv and i have checked and cleaned my pre filter. no leaks that i can see. idk if its my lift pump or if i have air in fuel,but i need help/advice on how to check and fix the problem i am having

 

Have tou turned the "smoke" screw to get more smoke?
Bigger injectors might get some puffs of smoke to help you tune...

 

yes i've had the smoke screw all the way in and out,still it doesnt help.i have some kind of fuel problem its just finding out what it is

 

What is your fuel pressure running?

 

i dont know i got the snubber in today now i just have to get a gauge to check

 

the truck runs fine it idles fine and runs fine no stalling or missing or anything but the power levels havent changed it still feels like it did when i got it from the dealership and it was ALL stock then

 

Pull the linkage off the side of the pump, and see what the 10-digit part number is on the Bosch tag. Better yet, just post all the numbers on that tag.

 

whats the tag/numbers correspond to if you dont mind me asking

 

It'll tell you what application it was from, as well as some details on the pump itself. Your pump may have been swapped from a different engine at some point.

 

908 pump
pes6p120a120rs7370-1st set
0 402 736 911-2nd set
76725 16789 thats whats on the bosch tag

 

Thats the correct pump for your truck. I'd make sure you are getting full travel on your throttle linkage. Pop the rod off, and make sure the movement you get on the throttle lever at the back is the same as what your pedal is providing. Adjust accordingly. Let us know what your fuel pressure is when you get the gauge hooked up.

 

Could be the prefilter being partially clogged, let enough thru that the truck runs OK, but not let enough to roll smoke.

Also I question the torktek, seems to be a few that don't seem to be what they say, mostly in ones that cannot monitor their fuel pressure, I believe they are adjustable?

 

Another thing to check...Make sure the shutoff switch is fully engaged..If its part engaged,the truck will run but will not get full fuel...I had this problem when I got my truck...

 

smoke sucks and just makes people mad, my truck barely smokes and runs amazing for what i have. i would just worry about smoking the car next to you and not covering the tree hugger behind you with smoke. thats my thought.

 

Perhaps your tranny is slipping not allowing the engine to come under enough load to smoke.
