I have question for you thats in the know...my hellcats putting out 17lbs. of boost I'm thinking about going to a 3bar map is that something I need to do or not?And if so do all (four) map's have to be changed?If they do I guess I'll have to figure out what in the tune that will to change also. Thanks

You mean MAP manifold absolute pressure, or map as in the fuel map as response to MAP and RPM? (alpha-N)

A MAP sensor or MAP gauge are other things.

@rookerrobert 3Bar sensor would be needed if you make more than 18lbs of boost as 2bar(In reality its more like 2.25bar) wont show past it .. But a tuner can work around it but you wont see anything above 18lbs on your dash. Changing the sensor all 4 of them will need change in tuning for the new parameters .

yes the manifold absolute pressure

You mean MAP manifold absolute pressure, or map as in the fuel map as response to MAP and RPM? (alpha-N)

A MAP sensor or MAP gauge are other things.

So you are going to 45PSI or so absolute, meaning you will be running around 30PSI of boost?

no sir going to 17lbs. it was 15 but when I installed the incognito it went up 2lbs. this what I found....
Bar to Psi Conversion Table
(Bar Psi [psi] 0.1 bar1.4503773773 psi1 bar14.503773773 psi2 bar29.007547546 psi3 bar43.511321319 psi)
And I might be guessing but I'm only using common sense boost is boost so the 2bar is 29.00
