Apexi AVCR or Greddy Profec B (Boost Controller)
 

Which one should I choose and why?

Neither,the Apexi is a fucking bitch to set up right and the Greddy profec is a piece of shit(unless it's the older version and not the profec b 2).

I would look into the Turbosmart E-Boost EBC or one from Blitz.

From what your sig says,you have a Hydra,why not just get a solenoid and have the Hydra control your boost.

What makes you say that?

I've used an AVC-R on my last three turbo cars, and there's never been an issue.

I have been using that, but it's less than perfect. Very easily could be me though. I have had nothing but problems when the temperature changes.

i heard hydra's were having the same problems with temp change as the MS.
MBC, bam chica chica Bam.

My post is totally unhelpful. :crx:

Good Luck!

Everyone I know who had one experienced the same thing,it was never a issue once it was dialed in,but it was a fucking pain in the ass the dial in right compared to other EBC's.

The Spec2 is baffling unless you use the writeup on evom.net

The ProfecB or Type S are great, easy as pie to dial in, and the B can be found for $200 used very easily.

No comment on the AVCR, I have one, and a Profec Type S, but haven't decided which to use when the time comes. I'll more than likely start with the S since it's so easy a caveman could do it.

i am using profec bII no problems here. you just have to set it up right

because you haven't bought an axillary EBC setup yet

I purchased the Apexi AVC-R today. The Apexi will be more involved to install, but it does offer more once it is setup. I will post back once I get it installed and let everyone know if I made a wise choice.
