i believe you are describing a problem a bunch of us had with rtek 2.x. Mine would idle in 12's AFR, cruise in closed loop (14/15 AFR), and 10/11's in boost. But if you cruise in very low vacuum like near 20in, it would lean out to 17/18 AFR and hesitate. a lot of guys are having this problem. i eventually upgraded to haltech, same setup, same injectors, same boost sensor but never saw the problem again. i suspect its an rtek programming problem, but never was able to prove it
