How can I tell if my s/c truck has a 7th injector kit installed?

Forgive me if this is a dumb question with an obvious answer, but I can't seem to find any info on this. As the title suggests, I need to know how I can tell if my truck is equipped with a 7th injector kit.

I bought my '04 last month and it was equipped with a dealer installed TRD supercharger, headers and exhaust. However, after much research into how the supercharger works and operates, I know it's in my best interest to have the URD 7th injector kit installed...but I'm not sure if I'm already equipped with one.

The truck runs and drives great, however I did throw a p0171 code last week (system too lean, bank 1) which makes me worried that maybe I'm running lean with the s/c because I lack the 7th injector kit? URD website says that their kit prevents high RPM lean out, and the code appeared one day after I had been running 6psi of boost on the freeway.

Anyway, if anyone has some insight it would be greatly appreciated, thank you!

 

For what it's worth, I cleaned my MAF sensor and cleared the code by disconnecting the battery and it's stayed off since (that was 6 days ago). But I'm worried that the MAF wasn't the issue and that if I run high boost again I'll run lean...hence my OP

 

you would see the injector somewhere upstream of the SC. also you would see the fuel line coming off somewhere.

 

So it's completely visible looking at the s/c? This is where I feel dumb for asking, lol. I just have no idea what it looks like/what to look for.

Here's a pic under the hood...

 

Looks so clean under there

This might help ya!

haha I was literally just looking at that same photo on Google image search right before I clicked back here

I actually found this one on the same search which had it labeled...I'm comparing to my photo and I want to say that it looks like I don't have the 7th injector kit installed? Still can't really tell for sure though I'll have to go poke around the supercharger tomorrow when it's light out.

Thanks for the replies!
