adjustable MAP sensor
I rebuilt my motor last year... 2015 actually. When i was working on it, i made the adjustable MAP sensor, to install when i built the motor. But, i never installed it.
When i rebuilt the motor, i port matched my throttle body to the 99+ intake manifold (that i also upgraded to), port matched the manifold to the head (which i also ported) and i port matched my apn header to the head. Im running 2.5" pipe all the way back too. Also relocated the ait sensor to the air box and opened up the airbox a bit to take in more air. I also installed neon injectors.
Would there be a benefit, installing the adjustable MAP sensor, at all?

I had one on my 4.0 and it just made it crank longer before starting and no more power.
That's something used more in stroker tuning applications.
