Jeep GC WK2 Tune pulling ST knock

Good to know theres no need for pump injectors or lines.

Pump and lines are good. Injectors are iffy. The 6.1 injectors flow enough. The 5.7 is another story. They do for a stock motor, but with mods, they're pushing their duty cycle.

Ok, quick update on mine. I adjusted it to the 91 tune and even put it back to stock mode. Both times, even in stock tune it was showing between 1 and 3 degrees ST knock. So I guess basically the engine was always doing it. I've put it back to the 93 tune and bought some Lucas octane boost. Couldn't find any of the NOS race boost. I then ran some pretty hard WOT runs up to around 100mph, it would only go up to about 3.5 degrees showing on the knock gauge. I've not seen anything over 4 yet.

Next thing I need to do is get a catch can. I may have oil or debris but just didn't know it and I've read on the forums that you should get this.
