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

look at my map, afgs, rpm, and inj dc it seems to fall on its face at 5700 rpm
what would make my afgs and map fall like that my 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

 

here it is in csv

is the maf losing resolution

 

I would add 2-4 more degrees of timing where you are showing 35-36 across the board.
Try that.

 

ok here are the files, the first one is with the rockers set looser not much change

now i went out and set them so loose that they make lots of noise now but there not bouncing up and down right there at zero lash i think. if you notice my map at idle is VERY LOW thats weird. whats normal for my cam

i thinking that some thing is going on like bad springs or bad comp r's
could this be an ignition problem i know its not the coil could be an opti.
im starting to think these lifters are the problem because the car has never run better while they are loose. I am going to try to adjust them one more time, looser because i might have one or two still tight but i dont think so
whats going on your about to see a big man cry

 

Stop what your doing and listen up.

I'll tell you how to adjust your valves.

1-Warm up the motor to operating temp.
2-remove driverside valve cover.
3-Start motor and let it idle.
4-Start with the 1st valve
5-Slowly loosen or tighten the rocker nut until the valve chatter gone - at this point this is called zero lash. When valve is at zero lash tighten the rocker nut another 1/2 turn. Do this for all the valves.
6-Repeat for passenger side.
