stock 02's have different readings so i need all of yalls help, i got a highstall (vig 3200) a shiftkit, hptuners and nitto555 tires since last time at the track and expected to be well into the 12's because my best has been 12.87 @ 109 2.0 60ft with the basics and i thought that i should just be faster after those mods but oh no i was mistaken, i was running around 13.8@100 with my little tune so i went back to the stock tune but killed tcm and the predator spark tables and started to lean out the power enrichment tables at the track and got better times (low 13's around 105 with a best of 12.87 @ 109 with a 1.8 60) but it seemed like the changes were erratic by the stock narrowbands on the histogram (each run loged and adjusted from that), so i go and check and the 02's look like they are off by about 100mV's per bank (bank1 803 mV bank2 924mv) so i am at a lost, could the 02's are bad or what???
thanks in advance

If they're that far off, you probably have an exhaust leak, or a bad o2.
Don't feel bad about your times though. The best I've run (before ported tb and finishing my tune) was a 12.8 at 111 with a 2.1 60' in 85 degree humid weather.
