What are we talking about a miss or hesitation feeling in 5000 to 6800 band?

I am feeling hesitation when im on third gear between 1000 and 2000 rpm , like it chokes but then it jumps after 2000 and feels great till the end .
Also on cold start when it idols i feel like it's doing misfires until the car warms up .

Cam specs? Sounds like normal cam issues.

The LTFT and STFT are both stuck at 1 they should be triming fuel either Plus or minus.

Email me your .csv log file, if you have your tune file that would be very helpful also

Please include all your vehicle info and mod list.
