Default Car Throttle hesitation help

If you see the video below it explains the issue I’m having anyone got any ideas, thank you so much. https://youtu.be/OwEkaNa_aBY

I’m not doing that with the throttle if I blip the throttle it’s as if it had a delay (goes from 1000 to 3000 jumps back down to 1500 then back up to 3000 all at once in a second)

Have you gone over the entire intake section including the intercooler and checked for vacuum leaks?

Usually these type of issues are not caused by ecu programming..

Check for leaks.

I have the original map saved and when I use that the issue is gone so that’s why I figured it had todo with that, you still might think it’s leaks?

Definitely looks MAF related, your short term trims are pulling a lot of fuel at idle. What year is the car and what mods do you have?

your MAF is all over the place. can you upload the ROM? your A/F is jumping around at idle which it should be pretty steady since its not under much load. Also, what does your target A/F tables look like cause your also pulling ALOT of fuel under idle. MAF scaling could fix this and your problem. But you're still pulling a lot of fuel out at idle which may need to adjust your target A/F. Scale the MAF and then move to next step.
