My vacuum was showing 0 under load with the JLT, I changed back to stock and new tune and I'm reading vacuum now.
The car is pulling like a fraught train
Thanks guys for the help, and now I know the 2012 intake is a smaller size then the 2015 newer
Under load the engine will have less vacuum. At WOT you'll have close to zero vacuum. Not sure what you were getting at?
