Injector ID question
Hello all, new powerstroke owner here, so sorry for any stupid questions. I recently picked up a 97 CCLB, and am trying to figure out exactly what I have. I got a good deal, so I was willing to take a little a risk on some unknown modifications.
The first owner had done what the second owner (that sold it to me) called a "hypermax conversion". When I asked what that meant, they said that it was something with the turbo and injectors. I have no idea if they knew what they were talking about (they probably didn't..)
From a visual inspection I was able to determine that the factory downpipe was gone, and what looks like a 3" downpipe is in its place. It has a 4" exhaust, but I didn't see a brand. It also has an intercooler with a hypermax flange at the turbo and hypermax y-pipe. It has one of those hypermax pyro boost combo gauges.
I am pretty that it has the stock garrett turbo.
Where I am not sure is the injectors. I am guessing stock, but am not sure. It puts out a lot of black smoke if you floor it until the turbo lights up. At about 5 lbs of boost (on the gauge, which I suspect may be inaccurate, need to check the line to it), the smoke clears up a bit, but still has a very visible haze. Max boost is about 15-17 psi. It pulls hard from 2000 rpm on up once boost starts to come up.
Does this sound stock? If I take off a valve cover, would hypermax injectors be labeled, or would I have to send one out to have it flow tested to see what I have? The main reason that I would like to know is for adding a tuner. Is it important what injectors I have in selecting a tune, or do you just use different tunes until you find the ones your truck likes?
Thanks for any help you can lend a newbie!
