Hey guys, I have searched around, but not sure about the answer.
I am looking for the one with the better response. I don't really mind about top-end speed.
I thought the GT2560 would be better for this, but then I read somewhere that it's the other way round??
It's for an R34 GTR with adj cam gears, AFMs, boost controller+PFC, 600cc injectors, pods, dump/split pipes.
Thanks for all the help.
