Hello everyone I'm having some trouble with my manual 2018 Mustang Gt. The list of mods I have are longtube headers with free flowing exhaust, jlt cold air intake , 2021 intake manifold with locked IMRC's and I have been tuning it myself. The car runs and drives great and pulls hard with the knock sensors adding in timing but recently it has started a little bit of positive knock near 7500 and today it saw a lot of positive knock on the 3 to 4 shift. I'd like to think the octane is there as the last time I filled up it was Shell 93 and I still have over half a tank. Attached below is my log and my tune. I am still new to tuning and looking for any advice, I just want to learn. Thank you!+Knockonshiftto4th.hplJuly_3_intcamtest.hpt
