Just want to get something straight. If im going to be boosting on the stock s14 MAFS, my boost limit is going to be somewhere around 6-8 pounds and then I can make anymore power with my MAFS because it maxes out. If i have the emanage with the pressure sensor will it take care of boost above that level so my maf being maxed doesn't matter anymore, or do I have to get a z32 MAFS.

No im not talking about hacked mafs, its going to be controlled by an emanage.

Doesnt the emanage read pressure like a MAP sensor, how does it work with our maf after it maxes out.

The E-manage read from the pressure sensor, it tell the E-manage the density of the air entering the manifold, and the E-manage adjusts accordingly, the e-manage ignores the MAF after it maxes out

would it be smart to go ahead and buy a z32 maf anyways and not have it max out and still use teh pressure sensor for tuning via load, or is it not worth the money if the pressure sensor is going to be there.

if you have a Z32 maf, then you simply don’t need the pressure senor, however consider the following

you will need to find one (easier said then done), pay 100+ dollars on it (same price as the pressure senor) the maf will be used and abused, and might not work properly, pressure senor is plug and play, while the maf will have to be rewired and accounted for when tuning.

going off topic, if you setup your turbo kit and all emissions crap is accounted for, can you have a setup that doesnt throw a CEL. Any of you guys running your KA-t like this or is it not worth it, shoudl i jsut ditch the EGR and take out my CEL so it doesnt bother me.

Checkered-Member thanks for the input

the only CEL's i have from my turbo kit off the stock maf at least was EGR and the second o2 sensor. i COULD have put the egr in the downpipe and i COULD have got the second o2 sensor int he exhuast. nether affect anything other than the CEL. not worth it in my opinion
