+170mV means less air less fuel and I think it will affect the timing as well

I made changes to CO-trim before and after i made changes to TPS.
When i had +290mV then i tried changing the CO-trim from +10 to +30 (Originally i had +22). I rode some time with +17 trim and had no problems (maybe only that engine got little bit too hot sometimes).
At the moment i have +170mV(+20 trim) and it rode very good, it had more torque (i got the front wheel off the ground much easily than before). But still the issue that it started to stall little bit too easily and very quick snap on the throttle sometimes stalls it too...higer idle should fix that in my opinion. I set the CO trim to +25 now and hope to test it out tomorrow.
But yeah i should say that +170mV gives more torque but with +290mV engine revd little bit quicker?(at least when listening with ear).
So i'm confused at the moment...i like the low end torque but if that(+170mV) gives too lean mixture then thats not so good either.
I checked the TPS with guzzydiag, and didn't see any dead spots (turned the throttle really slow and watched the TPS angle and voltage).
What else should i check? Replace injector?
