I just installed my 7x9 injectors and fuel (in addition to the other mods in my sig) and the truck runs awesome! and has plenty of ***** but doesn't blow any smoke at all.

It might shoot a puff out if I stomp on it when all warmed up but other than that nothing... ?

What does this mean? Is my truck just extremely efficient?

 

7 hole injectors will probably be alot cleaner than 5 hole. my 5x12's are 90 horse also, n they only smoke if i lug it. get above 1500 rpms n they clean up real quick. if u can make good power with little smoke, ur doin pretty good. but u might wanna throw a new fuel filter on it just in case

the guys at SDX really know what they are doin

 

So im assuming since in your sig it says 90 horse and 5x.012 are 90's they are supposed to be the same just swapping hole designs up? Im still catching up on this 7 hole stuff. Stock charger on the truck?

 

@ BRE

yes. stock charger and wastegate tuned to open at 32 psi :

 

what is your fuel pressure what are you seeing on your pyro at wide open throttle

 

my fuel pressure gauge is under hood and it reads anywhere from 25 - 30 at idle

my exhaust temp ranges from 1100 to 1200 when wide open

 

(dan) your timing is not in your sig

 

does it seem like it has plenty of power?
how much did it smoke b4?

where did you get 7x9 injectors?
how many ponys over stock?

 

i did the same mods at the same time. the 7 holes came from sdx. they should be around 100hp. they flow between a 5x12 and a 5x14. they didnt smoke before the mods but these were the first fueling mods done

 

if thats all thats done to the truck it probably wont smoke much unless you labor the engine

where did you buy the injectors at? now that i got my truck paid off im going to buy some performance stuff for it, after i get a trans
