I am very interested in one of these as well. Apexi makes the AVC-R where you are able to regulate boost depending on what gear you are in. I have never personally used one and they seem like it would be complicated to use. Other than being difficult to use I would still like to get one. I always have a problem with detonation in 1st and 2nd gear on High boost, no matter how much tuning is attempted.

Does anyone have personal experience with the Blitz SBC id? Is able to regulate boost per gear like the AVC would?

I would be very disappointed in Greddy if the Profec B II was not an improvement from the original profec’s. Either way, my next upgrade will most likely be the AVCR.
