what's better to use on a LS with a revhard stage 2c turbo kit, an XS manual single solinoid boost controller or the apexi avc-d, the electronic one and not the digital thanks.

 

greddy profec b or the XS manual is nice as well. i like the greddy profec b for ease of use and it works wonders.

 

profec b here

 

profecB is better cuz you get to adjust the boost inside the car. it beats having to run hard down the street and get out of the car, turn the screw, run it again, turn the screw, run it again, turn the screw, run it again, turn the screw, run it again...
