Log stock map and compare to determine if you have a problem or if you're being ambitious as you could just be out of fuel. You need to look at trims as well as low and high fuel pressures to ID if it's a fuel or air issue. Try their forum for JB4 support. N54tech.
Aside from a log or two stop pushing the car, if you're really at AFR 17+ you'll damage something eventually.
It's not the O2 sensors.
Did you put in new injector decouplers and seals?
Other feedback is the dinan coils are a waste of money.
