afr ratio at 70mph?

[m6z]

Just installed a turbo tweak street chip. Just wanting to know what the desired afr should be at 70mph with the cruise set? Running about 2300 rpm.

I know I'm shooting for 11:1 at full throttle, just wasn't sure what the cruise afr should be.

Thanks for the help,
Doug

Well, you should still be hoping for something around 14.7:1, assuming the chip is in closed loop and all is working correctly. Unless it has a lean cruise mode.

Thanks, that where it at now. Just wanted to be positive before I drive it 100 miles today.
