Do you own your own shop for installing VAFC? If so, where are you guys located? I bought one awhile back and tried to do the install. Half way reading the instruction, I pretty much gave up. Too many color coordination. If you can do a decent work, the job is yours. I'm in Tustin. PM me....circuitsports said:I have a couple on two cars I own and about 25 more that I have installed and every single one does a very good job of increasing power and tq. However although I install them I do not have access to a dyno at my location so I send cars out to a location that does and has recieved APEXi certification on tuning these. Otherwise you can make avery quick mess of things as these are deffinately not toys.
