Microtech/TPScal issue?

Hello everyone. I am having an issue with my car that I can't really diagnose. I have a feeling it is something to do with my TPS cal because it didn't do this until I started messing with it.

the physical symptom - When starting in 1st gear I get on the throttle a bit and begin to let off on the clutch. The car moves a bit but as I begin to pull out further from the clutch/throttle more the car wants to die, unless I mash the gas. I know it sounds like i'm just stalling the car but i'm not. I already drove it before this and it didn't do this.

What I did (but I am confused). Is I went to the TPScal screen. the % read ~45%. So I hit the red button and adjusted it until the output read 00%

As I get close to 00% the screen looks like this

Opt TPScal +20%
+01% PG Crank

Then when I arrow past that the screen goes to:

Opt TPScal +21%
+00% PG *7.05 sT

If I keep going up the bottom goes back to crank.

First off what the hell should I be setting it to? The manual isn't very descriptive.
Second what does 'PG' mean? *7.05 sT? i guess its just not clear what all this means.
Third does this sound like it may be my issue?

I appreciate any help in advance.

You need to adjust the TPS screen until you see the astrisk.

But it doesn't sound like a TPS issue. Sounds like the low end of the map needs tuning. Do you have anyway to monitor A/F ratio? What happens when the car wants to die?

Agreed with aaron, adjust the fuel at the rpm thats having the problems, i had a similar problem when i began tuning.

Pretty sure the "PG" you are talking about is "Program" or "program mode"
