Right the boost control is currently controlled by an HKS EVC.

When i has going round Knockhill hill yesterday i noticed It wasn't always making proper Boost.

Sometimes it would jut go to 1.6 bar other time it would reach its target of 2 bar. What i was wondering is this problem just down to this electronic boost controller?

Should i just go Air to air?

What is all the items i need for air to air? Any adjustments needed to the ecu to run this??

 

EVC is a pretty old model, but should still work ok if setup properly.

I'm using a Greddy profec b in a 4x4 Cossie, and it works perfectly. Air-Air is a lot of hassle and expense, when a decent EBC will do the same job, easier, and cheaper, and give the user easy adjustability.

 

Cheers. So do you think its probably down to being badley setup. I have just been using it in Auto mode which is set to 1 bar low - 2bar high.

Should i try using it in the manual setting???

Considering switching to an AVC-R

 

It could be.... its just a case of playing about with it, to see what works best, as every car is different.

I'd stay well clear of the AVCR, far too much hassle to set up.

 

Thanks for the advice mate.
