I just switched to the ebl p4 flash for my upcoming blower install. Here are current pictures of my ve tables low, high, and extended. I am completely new to all of this tuning stuff. What do you guys see is going on here? The car feels like it is down on power.

What you are seeing in the VE tables is normal. With the cam, intake, heads and so on the VE is lower at lower RPM and greater at higher RPM.

The VE of an engine will follow the torque curve.

You do need to flatten the low RPM and MAP area of the low speed VE table. Check about halfway down this page (look for the images):

Note that it doesn't get flattened to 0, but to the lower end of the learned in area. Which is the valley you see.

Alright, I will give that a try. One other thing I haven't figure out yet is where do I go to adjust these values, •"BPC - BPC vs VAC"
•"BST - BPC vs Boost". I am looking through tuner pro but cant seem to find where these are listed. I also searched but cant seem to find the formula to calculate bpc either.

The EBL P4 Flash system (and SFI-6) use individual injector flow rate and engine displacement parameters. No BPC table involved.

The lower end of the learned in area would be the 50 kpa 1000 rpm area? The VE is only at 10.59 there. That seems like a very low number to me.

Could that low of a ve number possibly be my start then stall/running lean condition like I talked about in my other thread?

The VE is a little on the low side, but it is expected to be. If you think it is causing the stalling lean issue, bump it up some and try it. Recall that it only takes a few seconds to flash in a new tune.

This allows you to try stuff in a short period of time.
