You never got any other data on the injectors ? I would definitely make sure that you have the correct data put in for them. As for EIOT when I tested it out on eehack it blew my mind on how much it changed my fueling for the common big cam problems mind you I've only tested it at idel because of it being winter here. Now my ve tables needs a major re maping. I have a pretty moded LT1 and so far so good. But have more to do to get it perfect. And I just want to throw a thank you out to Ivan and Steve for all there help and the awesome programs they have made to make life of tuning easier.
