I use a AVC-R there prone to over boosting when the weather is very cold.. Not such a bad thing but personaly the price you spend on a decent boost controler could go
into getting yourself a decent computer system so you dont need to run AFM's and that can run the boost from inside the car via a Digital pannel.
about 2200 for a really good system Mark at Godzilla was talking about them the other day. Personaly i know ill be changing to it when i get my next GTR
PS: I love this pic got to put it in my post lol
