    2020 Durango 5.7 Procharged WOT issues

    Hey guys I have a 2020 Durango with P1SC 7PSI kit Procharger on. Typically I can go WOT from just about 1st but if I'm either in another gear like trying go WOT on the highway the engine seems to cut out as if it's some kinda rev limiter. The exhaust pops and sputters as well. This is usually around 4k-5k RPM. I have NGK Iridium IX LTR6IX-11. They were gapped to .035 and then after reading it seemed I may have had blowout so I lowered them to .028 but doesn't seem to be helping. The engine is tuned but seems whatever the issue is it doesn't appear in the log correctly or something. I attached a short little WOT. It's short just trying to capture a quick WOT. I'm new to HPtuners more used to Diablo. So if anyone could point me in the right direction. Trying to avoid blowing anything up lol
    Edit: For anyone looking at the log I'm not showing any boost or much boost because the vacuum isn't dropping correctly because the issue I'm facing causes the bypass to not close. I plugged bypass and drove then I was seeing boost correctly. But my issues at 4-5k still where there at that time

    I'll give that a shot. I'm very new to HPtuners so I just logged whatever was showed up when I started the program. I need to get a wideband I just started getting this kit together. I don't know much about WideBands but I know they are highly recommended.

    This! I do several free tunes from the forum, but I'm not going back and forth with logs and revisions for free. For a paying customer, Ill build the file but will not send until payment is received

    I can understand why some dont wanna pay because shit ive been threw in the past with all these tuners think they know what there doing and end result is, they just dont have time to deal with your problems and you get pushed off with half ass tune because they would rather take more money from some young kid give him one that lets car run and thats it your done.
