Hi everybody need a little help here is my datamaster run
http://www.sharemation.com/stllt1/383le3heads.uni

If you have datamaster look at my map, afgs, rpm, and inj dc it seems to stall at 5700 rpm. My map drops to 91 and maf says its not breathing evenly like up and down what would make my afgs and map fall like that. I was thinking that it was a couple things a spike of too much fuel or my spark is weak my coil and opti has 6k on it everything is brand new on this car. what do think about the fuel inj dc 85% at 5900 rpm is that to much with 36 pound injectors???? i have no misses up top. no black out the back and wide band is at 12 to 1. but i might have a header leak. i really dont think it is valve float because of good springs and comp r. please help car only went 12.4 at 109 mph????

 

anybody

 

dont know much about wat ur talkin about but i had my z stall about 53 52 but ran hard to get there...found out it was a bad connection on the alternator wire sharging the battery??? WTF i kno...anyways worht a try checking, coil possibly cant reload power that wuick idk
hope that might help
