If the gauge reads "10" then, regardless of the actual A/F ratio, it is still below the Accurate operating threshold of the NB sensor, which according to your website link, is approx 14-15, which means that the engine is recieving enough fuel, albeit not the correct amount for MAX POWER...
So your quote about saving for a new motor is entirely wrong, because aside from pre-detonation and knock, more fuel will not hurt it...
Also, I noticed plenty of threads on here about how Uberdata and such things are difficult to tune, and after they think they have it tuned, it acts up again... I don't want a headache, i just wan't a semi-reliable KIT...
I live in PA, and I've asked about so called "tuners" in this area, but everyone around here are idiots, I know way more than any shop around here...
They are all audio-bullshit stores, they'll sell u an intake and maybe put it on wrong, LOL.

Using the stock NB o2 sensor to tell you any vital information is just dumb and stuipid. The further you get away from stoich the less accurate the sensor is. So if your shooting for a 12:1 afr (like you should in boost) it will NOT give you an accurate reading. His comment about you saving for a new motor could be correct if you base your fuel requirements on what your NB o2 sensor is telling you.
I've experienced it first hand. When I swapped turbo's (to a larger one) my afr went through the roof. I knew this because of the way the car responded, but my afr gauge read that I was still lean. I corrected my problem enough to drive it to a dyno, strapped it on and leaned the afr out from 10.0:1 + to about 11.9:1. Still my afr gauge would read lean and rich when I know my afr was between 11.8 and 12.2 in boost.
It is not an accurate tool for telling you how your boosted engine is doing. You must have a wideband 02 sensor and meter if you want accurate reading.
Keep being stubborn and you will end up needing a rebuild, thats a fact. I don't know why you posted on here if your going to be stuck in your ways, and not listen to the advice being given to you.
