Recently i have bought some injectors from SDX stage 3 (140hp) And i finally got them in over the weekend. first time i fired up the truck, the idle was real rough like at 2000RPM, and you had to keep your foot on it to keep the truck a running. There was a heavy haze at the tail time.Took it out the road and they felt like stock injectors starting out, but once the engine got alittle warm they performed alittle better. Got to alittle straight strech and just layed on it. Roughly going from 40-45mph to 60-63mph within 130yards (which i think, it can be better) The next day, jump in the truck and started it and the idle was the same at 2000RPM real rough and there was a haze.And they still drove like stock injectors until the engine warmed up alittle. With my stock injectors it started at 7000RPM and alittle rough. Am i doing something wrong or does it sound like the injectors are defective. Im not disen SDX, but if i pay alot of money for something. I want it to run properly.

 

7000 rpm? im guessing you mean 700? and 200? clear that up for me. do you have the fuel and air to back it up? you can put stage 3's on a stock fuel system and stock turbo but it wont be good.

o my bad just read your sig. so it looks like you have an airdog and thats it? that would be why

 

Whats your timing at? Also what thinkness washer did you put in? Also whats your idle at?

 

Also got alittle pump work done too. Sorry bout the rpm but that is correct 700 and 200.
The idle im not sure. Im gonna have to recheck again. The washer, i used the medium size washer and idle is at 925

 

thats weird about the idle but i'm guessin you dont have the air to back it up but it should be rollin coal. is it?

 

itll blow it but once i get in 5th gear, itll back off some. Whats roughly the boost range with theses injectors? The highest ive got it so far is 30psi

 

Whats your timing?

 

i'm waitin for scott or ......... oh what the hell is his name...Luke to chime in but from what i've seen when looking for injectors for my truck you do not have the air to back it up. i think stage 2's say they're for if you're planning on upgrading your turbo in the future so i'd say stage 3's want a new turbo

 

Im gonna have to recheck my timmeing.

 

am i wrong? stage 3's too much for stock turbo
