haha the old objectivity debate hey.... FYI i have been using, selling and importing this gear for around 10years (all my comment s are based on experience not oppinion) and i have sold shit loads of them but for the money you can do heaps better, some people just dont want to listen and in this case their custom is what becomes important.
on a GTR, twin turbo supra etc the PFC controller has issues controlling the initial boost surge and the boost curve is fairly erratic, up top it is fine but you cannot tune out the initial spikes and troughs something nearly all other boost controller can do easily especially when you look at cost;
average sell prices on it s competition... for the same money you could get a GREDDY profec or a bit more you could get AVCR, BLITZ spec R or IDIII
PFC controller; $399
Profec B spec II $330
HKS EVC V; $575
AVCR; $495-580
BLITZ spec R or IDIII: $400-525
Gizzmo MSIBC; $399 atm
Gizzmo IBC $269 atm
Az_Stryder; If you got it use it simple as that.
