am look at a greddy profec b spec ll and a HKS EVC 4 wat is the major difference ? the hks 1 is about 100 buks less, just wondering which would be more suitable for my setup

i have the greddy one.
have had no issues with it at all. its easy to use and works great.

has a great function that if you exceed a set boost pressure it knocks it back by a certain %. in my case if i go over 21psi it knocks it back to 17psi. had me stumped the first time as i had it setup at my first tune, and didnt realise it was set like that. no matter how much i turned it up it wouldnt go over 17psi, until i turned it back down under the threshold

also has a nice pretty screen , can have 3x setting, off, low and high.

has a great option that is a remote steering mount controller, think its like 150$ extra, but it straps to the steering wheel and has a button so you can switch between low and high on the fly. is wireless and a reciever plugs right into the back of the unit. great for drag racing as you can keep boost to say 7psi and only change up to 20psi only when the tyres grip. its kinda like scramble boost except you have control of when your boost level goes up.

no experience with the hks one sorry.

I had a hks evc2 and it was just awesome. It has a boost learning function which you have to set up using first second and third gear. The manual explains it quite well. It has a high boost and low boost function and also has a scramble boost mode that you can set how long you want it to scramble for. Ill be getting another one of these as soon as i can.

plus one for profec here.

would 250 be a ok price for a hks evc 4?

[TRD_ZERO]

Yeah id pay 250 for an evc4 does it have the manual? If not you will be able to find it online somewhere.
