93 Octane

Looking to get some insight for my F30 335i. I was running a Stage 1 OTS map and around the 5000-6000 rpm range the car started to violently jump and almost had an anit lag type of back fire. I spoke to a tuner here at my shop and he said it looked like my HPFP wasnt running correctly and my throttle shut as well. I switched back to the Stock tune for my car and just adjusted a few things like slight burble. I just wanted someone to take a look at them and see if i am okay now. I have no idea what they original owner had my car set to.
