Hi,

You all who have a HKS EVC 3-5 or a similar device istalled in your Scooby do you think it was worth the money ?

I currently have a mechanical relief valve installed to control the boost but I'm a bit disapointed with its ability to keep boost level stable.

Definately worth the extra cost.

Even more so if you can find one 2nd hand.

I like the HKS EVC3 and 4.

EVC III is a classic, haven't tried the EVC IV yet, but I might.

Drop me an email if you want a used one;)

HKS EVC IV, very good piece of kit :D excellent boost control ;)
