Guys I need help with a lean hesitation, for a tbi 305. Has 081 tpi heads, lt1 cam and some other mods. Runs good when started cold till the temp gauge gets to about 140 degrees then hesitates. Once warmed up to 200 degrees runs good again. I get a hesitation when accelerating the more throttle the bigger the hesitation. I have the fuel pressure and blms tuned close to ideal. What table should I adjust to get rid of that hesitation. I am using a painless harness and 7747 ecm.
