Hi, I am new to tuning, and I am pretty Knowledgeable with stuff and like to learn all i can, probably why i question the tune in my car. I think overall it drives good, if i didn't know better. After looking at logs it made me think, Boost is fluttery though. I have a 2016 Charger scat pack, I had an e force 2650, headers and high flow cats installed by Petty's garage. After pulling the trigger and doing some research. I learned about the 392 pistons. I was told by them its all in the tune, we've done dozens with no issues. Well the tops blew off two pistons in less 4000 miles, i was just cruising at the time at 25 mph. I brought the car to them. They said they would help me rebuild it, which ended up being a hassle and a long story, that's taken care of. Needless to say my experience was bad and have not heard good things about them since. The engine was rebuilt with forged pistons, and had them install a comp cams custom blower grind, which i don't know the specs for and asked for them several times. Few questions I have is. The rear o2's are not set to enable. Is that normal? Boost flutters at part throttle, at WOT it bounces up and down 2 or 3 psi. Doesn't seem right to me. Fuel trims adjust a lot it seems at part throttle. I am getting a little knock and it seems to be running a little lean, running 93 in it. I have a WB installed. Just curious if someone wouldn't mind taking a look, for a second opinion, my being the first which I am just learn so its not all that good. I am talking to a tuner near me, but there a super busy right now. Waiting on them to send me channels they want me to log. They also said they had to fix a few of petty tunes. Thanks
