How much should I lean....
I just logged a 1-4gear pull and the O2s were .989 and .991 bank 1 and 2 sensor #1. How much does the car need to be leaned out? 5%?

you can't go by the O2's from the factory. You need a wide band sensor. Yes, you are rich, but the OEM O2's give you no actual measure of how rich.

you really need to get the car on a dyno to answer that question :seeya

Wide bands and Dyno would be best, but you can get pretty close if you watch KR and total timing. I got my engine back and was able to get back in the 10s on Motor only after 1 adjustment to the injectors and a couple of runs down the track. Keep it rich for Nitrous, about 950 and watch that KR. Good Luck.
