Resolved Fuel cut when i touch throttle (video)

So what i did recently was: JB weld my 3 vacuum line off the TB because my caps were rotted. I also installed Speed Density meaning i had a bung welded into my UICP with the GM IAT wired in (i cut the red wire with blue stripe and the black wire in the MAF harness to solder into the sensor pigtail) I also have the Omni 4bar Mitsi style MAP installed and all of this was programmed into ECMLink.

I tried back tracking to see if it would stille do it: Put factory MAP back in and remove it from ECMLink. Turn the MAF sensor back to factory too but since the GM IAT is wired in still im wondering if the black wire i cut is effecting the MAF reading causing this fuel cut.

I know some of this may sound confusing so ask questions if need be.

Also: i checked, there is no boost leak.

If anyone is familiar i can post a ECMLink log of this too

wait.... i think i figured it out..... i spliced the black ground wire back into the MAF harness and throttle reponse came back to normal...

Was the wiring bad on the factory mdp harness?
