Car running lean...

Car running lean...
My Z's been running very lean lately..my exhaust tip is as clean as new...
I plan to take it to dyno, but I'm pretty damn sure the car is running lean.
My mods are JWT pop charger, 5/16 plenum spacer, and Nismo exhaust.
What additional mod will richen up my car besides ECU reflash?
I'm staying away from ECU reflash because of a bad experience in the past.
Unless I absolutely need it (ie header, F/I) I will not consider this option again.
Also, it seems like my pop charger is sucking in WAY too much air..

Prob only other option is a piggy back, like Utec. I just got my ecu back from AAM for a reflash, because mine was running lean after dyno. I haven't had a chance to redyno it yet... Can you tell me some of the negative experiences you had with a reflash?

technosquare and aam standard reflash is about $600, but its more for a custom dyno tuned reflash (at aam anyhow). I wouldn't recommend going that route unless you aren't going to do any other performance mods and are able to bring your car to them to do it.
as for the piggybacks, the EU and UTEC seem to be the current favorites and I'd definately recommend the UTEC if you plan on going FI. however any of those options are pretty expensive when you account for dyno and tuning time. if you don't plan on ever going FI and are only concerned with getting your A/F corrected then I might go with the emanage blue and have an experienced shop dyno tune it for you.

thats a little scary...i was going to order myself a spacer soon also (i already have the pop charger and nismo) but if its gonna cause me to run so lean i need to mess with the ecu im not so sure anymore
im running rich right now, my tips get pretty black on the bottom side in about a week.
is this normal for his car to be lean after only these couple of mods?

My tips are black as he11 on my car, and I found that it's running lean as well, but that's under boost w/FI. So it's more about whether the car is running lean or not under load.
