Acceleration Enrichment?

[forbix4]

any suggestions on where to start, how much can you change it?
I am getting a lag when shifting hard on the throttle gets worse as it goes through the gears.
do you raise or lower the ae tbi/ map filter ratio and by how much?

gm tbi, 496cid, vacuum ref fuel reg, man trans, using tuner pro.

There's 2 main AE tables to adjust.
AE vs TPS is for instant AE and the AE vs MAP is the long term AE.

What setup do you have and what bin are you using?
What pressure are you running and what injectors?

How is the vacuum regulator set up?
Does the pressure increase as the vacuum drops with RPM?

It almost sounds like you are going lean under a load.
Got a data log and BLM?

I actually have several issues, but am trying to work through them. i need to check the gasket at the tbi i think i might have a vacuum leak, my last data log is about 500 miles ago.

i am using dynamic efi's EBL, I have a 1227747 ecm running my 7.5l v-8 tbi ,EBL_F_2012.BIN: L19 7.4l, 4-spd, '89 2wd/4wd 3/4 & 1 ton truck, the tbi was bored out by arizona street and marine to flow better, the injectors should be #81's it was a stock 89 suburban tbi and i pulled the whole package

Aeromotive 1330, yes as vacuum decreases fuel increases, i have the light spring installed and its almost all the way in, i think its around 21psi

i have not figured out how to post the data logs from the ebl wud, i will run a new data log in the morning and figure out how to cut and past it

You can right click on any file and "send to" a compressed file. Then attach that file.

cant seem to find the vacuum leak, it is a squel or whistle, it comes and goes. sprayed carb cleaner all around it and changed the base gasket. idle is still high avg is 850.
I attached the last data log and my bin file.
