[QUOTE="JDAZGuy, post: 1554592, member: 42406"] Hi All, I tried to find posts similar to the issue I'm having but not finding enough specifics to point me to a cause of what I'm experiencing. So apologies up front, if this is asked somewhere on this forum and I missed it. Yesterday I had an Edge HT2 Tuner installed and a S&B Cold Air Intake on my 2019 SCREW. They had set the tune to the 93 Octane tune and I have 91 octane gas in the truck. I didn't get a chance to really test it on the drive home but definitely could feel the difference in power. Today I went pheasant hunting and on the drive out I opened it up to see what it could do. I quickly got the yellow wrench light. I pulled over, turned it off and the light went away, so I continued on my way. The area I hunted was very dusty and after the hunt (got 4 birds) I started home. As soon as I got up to speed the turbo started a very loud whistling noise, it didn't have that until after the dirt roads today. Worried that I would be stranded I pulled over and set the tune back to stock. The loud turbo whistled continued with the stock setting and within about 5 miles from home I got a check engine light and very bad idle and acceleration. Got home and plugged the Edge tuner back in to check the codes. I have P0300, 301, 302, and 303 DTC codes. Engine misfires on all cylinders. I've read the posts that suggested maybe an air leak or that I now have an imbalance of air pressure form the CAI. Just not sure how to isolate it? The truck never went into limp mode but its bad enough I don't want to drive until I figure this out. Is the tune not compatible? Is the CAI throwing my sensors off? Do I need a modified exhaust to have a CAI? I just wanted a bit more performance but not at the expense of my truck being reliable. Would really appreciate some insight from you pro's. Thanks [/QUOTE]
