Tune or not to Tune?
First off I know this is more of an EM question but we know how slow that forum moves. So I'll ask it here if someone wants to move it then so be it.
I just got the zeitronix and am datalogging rpm, map, and tps. Did a few runs yesterday and my air/fuel in boost are in the high/mid 11's almost all the way across with a little dip into the mid 10's at around 5-5600 rpm.
My question is, am I going to get any more power out of tuning it up to low 12's?
Or is it fine the way it is?

Re:Tune or not to Tune?
you might make a little more power, that's a little rich as is and you make more power leaner, so 
hell, if you have all the proper tools and know how, lean it out and see how it feels, if you don't like it, just reburn your current .bin here's a good chart of where you want your afr's, about 12.5:1 for the tip in to boost, then 12:1 the rest of the boost table is ideal......

Hows that Zeitronix working out for you BTW? You'll be the first person I'll hear an opinion from about that. I've been considering trading up my PLX M300 for either the LM-1 or Zeitronix's. I need something with dataloging. Uberdata's dataloging function is useless with my old and slow laptop

The zeitronix is just awesome. It's one hell of a deal. It was pretty easy to hook up and datalogging in no time. If you read this thread:
https://www.homemadeturbo.com/forum/...threadid=27347
You'll see where we figured out how to read the map sensor so you can even datalog boost without buying their expensive boost sensor. You get to datalog rpm, map, tps, and afr for $270.
