You might have a bad MAP, ICP, EBP, or other sensors. Might have boost/pre turbo exhaust leaks. Different gears, driving style, idling, manual/auto trans, possibly worn out injectors, not a great HPOP. Many many things can affect it. Now, I highly doubt they are getting 20-22 either.

Just cause they're "exact", they really aren't. They been used differently, wore out differently, everything.

12 still seems a bit low, get frustrated when I get under 15.

You'd need to get some monitor like AutoEnginuity to watch the live data feed from the sensors to see if they are in spec or not.

Drive slower and accelerate slowly, don't floor it.

Gun control is like trying to reduce drunk driving by making it tougher for sober people to own cars.
