I didn’t bash my firewall I had that bung welded shut and a new 02 bung welded little farther down where there is no clearance issues.
It is hot here in Vegas lol my IAT temps are often if not always above 104 lately. Once I’m cruising they are usually 10-15 degrees Above outside temps. And lately the outside temps when i drive are 95-110. It will be dropping to high 80’s next week so maybe I can get a wot pull in the morning. See if there’s any difference.
