I have an avcr.

.

.I installed it myself in a few hours.

.

.piece of cake to use.

Set how much boost you want and turn the injector duty cycle up/down untill you've achieved it.

.

.I have never felt the need to mess about with ne-points and trying to achieve a

"boost curve".

.

.foot down.

.

.lots of boost.

It also has the abillity to monitor/display 1 or 2 functions at the same time, I have mine set to show me boost and rpm.

.

.also gives you the peak amounts that you've hit so you can see if your over/under boosting without having to take your eyes off the road.

.

.lots of other 2'ers use them so it's easy to find out info on them.
