Hoping for the best , expecting the worst

[Juju5.0]

So today was supposed to be a very happy day for me , i took my baby to get dynotuned . The night before i had to replace a sparkplug cuz the check engine light came up. But it came up again and i had oreilys scan it and they said it was just random cylinder misfires but everything seems normal.

so i went to the tuner , a week ago a stock 10 speed 19 buddy went to them and he put down 393 to the wheel bone stock .... me with a k&n intake and exhaust setup only put down 380 , and my rpms stopped at 7000 instead of 7500 . Plus cylinders were misfiring... so the tuner barely got me to push 404 to the wheel which is obviously horrible so he just flashed it to stock and said come back when its fixed..


im hoping i take it to ford and all i need is a engine tune up and just some new spark plugs and its not something massively expensive that leaves me carless... ill find out monday

Should have done a crank re-learn. I might think about finding a different tuner.
Assuming he did not do a re-learn.

Zmodmotorsports in Sacramento. Ive seen youtubers go there and recommend them , people i know with mustangs all recommended them. They had mustangs of various years there that they were working on and they do more then just tuning so their reputable

What tuning device do you have?

Theres a throttle delay sometimes that usual cost me if i ever do roll races. . And sometimes it feels like the cars “shaking” or has the jitters after doing a pull or race. Im only 18 so im not to knowledgeable on cars. Bought it used at 42k miles , has 55k now , never got a tune up before.

OK, I was going to walk you through doing a crank re-learn.

Well the good news is i still have full coverage warranty so whatever it is should be fixed . Just hoping it something simple rather then big

From what I've seen most times when a P0300 code is set a crank re-learn fixes it.

Hopefully that will set you straight.

Yes the tuner tried that. It didnt work. Also i had 18 degress to detonation (on 91 costco gas) which he said was really bad. Taking it to ford tomorrow. Tempted to just get a 21’
