I did a review on the AVC-R vs the SBC ID-III a few years back...
You might find it helpful... I personally believe the ID-III is probablly the best money can buy, they just so realiable and easy to use...
I Also agree with Paul, the AVC-R can be very touchy with high boost applications... Most single solinoid controllers face this issue when using a high gain...
Anyway, link to the review I did ---> http://www.skylinesaustralia.com/forums/SB...ml&hl=avc-r
