I would really like to run the HKS EVC VI but it only controls up to like 36 psi. My other options are to get the aem solenoid for my ems but the main drawback to that is that it's not easily adjusted. Choice 2 the turbosmart E-Boost 2 and three the world motor sports PBC-1 here is a link to the PBC-1 WORLD electronics Pro Boost Control PBC-1 [WEPBC] - $377.00 : WORLD Motorsports Online Shop What one would you choose and why.

 

Why not just run a manual boost controller?

 

hks evc 6 the whole way... love the ebc...

 

Apexi AVCR, tested and reliably holds high boost well, on top of that if the solenoid gives way you can purchase a replacement ~100 bucks. I actually used EVC5, the solenoid gave way and im not able to find any replacement whatsoever, tho EVC is easier to use
