Default N20 Jerky acceleration at part throttle/pedal - 08-01-2018, 08:10 PM

I have a JB4 on my n20 428i and I've been having jerky acceleration at like 30-40% on the pedal. If I floor it, it goes away but as of recently has gotten worse and jerks at high throttle too. I ran map 2 for the first week and for the past month have only been on map 1 (about 700 miles since install). I have wagner ********* as well. I'll post a log I took. Let me know if you need any other info and thanks in advance.
