Maxing out n/a injectors?
So today I went out and logged some afr's with my lm1. I do not have the rpm converter yet so I have no rpm readings unfortunately. So what I did for my logs is I would hit record at like 1 to 1.5k, floor it and go WOT to 7 to 7.5k, and then hit record again to stop it at that point. Did this 3 times to give me an idea of what my afr's are like.
Well, I'm lean
Below is the pic with all 3 runs overlayed. The bottom dotted line I'm not too sure why it was so rich, I think that had a bit of the idle logged whereas the other ones were actually going WOT. Anyways, you can see I'm getting fairly lean hitting 14 to 15 afr's. Those 2 lean bumps there are somewhat worrying, but after that the ratios richen up a lot. I'm going to do a better pull on the freeway where I can actually go faster without breaking the law since these were taken in 1st gear (not the best for data). But how does this look so far? Seems a bit erratic and lean.
Suggestions if any? Link to mods are in my sig if you're curious.

like u said, I'd say u should get some Solid 3rd or 4th Gear pulls in where the engine has some real load on it.. and perhaps a Passenger that can do the recording for u, or even read it out loud as u go...
1st gear is so bloody short i don't see it being that useful for tuning ... (even more so for Turbo cars)
U have an SAFC and a fuel pump... I don't see how u could be maxin out the injectors this easily...
try to get some 3rd/4th gear runs in I say.. then see how those look
I say ur lean cuz of tuning not IDC% being too high

Yah when I can get my friend to come with me onto the freeway I'm going to do a 2k to redline 3rd gear pull. S-AFC is untuned and the fuel pump is just the stock turbo one, not making a huge difference.
