Mine doesn't have a delay
The TransGo -3 setup has a delay that I can do some work on and mostly eliminate, however there are some other quirks that pop up.
It opens up too much opportunity for a crossleak and a pressure leak IMO and this causes some of the issues. It also has a LONG restrictive circuit for 3rd gear and it makes too many changes to some of the stock circuits that are needed to kick shift valves "off".
Our "manual valve body" is a couple of minor VB mods and an electrical control that causes full manual operation.
Our transbrake does very little modification to the stock circuits. Pretty much minimal as you can do and still have an effective transbrake and firm shifts.
This is the key to it's success, reliability, effectiveness, and speed IMO.

Okay so someone clarify somthin for me.
A manual valve bodie or mvb makes the 80e FULL manual as in no overdrive???
Are there benifits to this??? Does that basically make it a 4 speed th400???
And can't you just downshift a regular 4l80e??? So what's would be the difffence??

If you don't have a pcm that will run the trans you have to spend $1000 on a controller that will run it.
Manual valve body means you have to physically shift it into and out of every gear. Put it in 3rd it will start in 3rd. Put it in 4th it will do that same thing. Some people get annoyed driving a mvb trans, but I have no issue with it.

You can floor it then down shift, if built it'll handle it just fine
