[QUOTE="PaxtonShelby, post: 15987551, member: 112637"] Much of the country has a problem with shit gas. I had to go to three local stations before my knock went away while bone stock. I’d recommend running it down to zero miles to empty, then dumping in 5-10 gallons of 110 unleaded. Drive it for 20-30 miles like you stole it. Now datalog again. It will likely add more timing. If that’s the case bad gas was your initial problem. If the knock sensors are still pulling timing then focus on the exhaust system. [/QUOTE]
