tuinig a t25 w/ afc worth it? here's my log!

[stevew1]

I was wondering if i could get any gains from tuning my t25 with some basic bolt ons: 3 inch exhaust, intake, rre upicp, boost @ 16 psi, 55 degrees F outside:

i wasn't sure what the difference between O2 bank 1 and O2 bank 2 is, which one is the one in the O2 housing and exhaust? Which one is more acurate to read? here's my log, is .98v rich? thanks, this is a 3rd gear pull.

also, i was reading the tuning tech article and wasn't sure how to tune the low throttle points. following what's written, i free revved to points between 1k-3k rpm but the fuel trims just keep changing so i don't know what to base changes on. how do you guys tune the low throttle?

o2 1 is the one you focus on. You log looks fine as you won't get more than 16 degree's unless your taking out alot of fuel.

Also considering your on the stock Injectors leave all the low throttle stuff at 0.
