ross - I only know of TOSHI from these forums as having chipped an R33 GTST.
costs more than the r32 though as they can't be remapped on to the chip where as the same chip can be over writen on the R32 or something.
send him a PM and see what he has to say.
however, If I had an R33 gtst, for $950 or so, I would just save till I got that power FC.
if it was the same on the R32's then I'd do pfc for that too.
but it's closer to $1400 for R32's...
JAYCAR DFA is Cheaper than safc yes - Better? I doubt it is actually any better.
I'm sure SK posted that it doesn't actually do anything more or less than an SAFC.
and since SAFC second hand is under $300, I wouldn't bother trying to put the JAYCAR kit together myself...
