This is why you tune in 3rd and 4th...also you'll get much more data per rpm range in a longer gear.

the timing was lowered due to knock

for good measure I often make 3 or 4 pulls in 4th gear back to back and then tune out the knock. This ultimately gives me a margin of safety.

The 2.3 consumes more air as seen with 1600hz by 5000rpm, stock turbo?

pfft, no one ever listens to me.
