G'Day jososo, welcome to the forum
Great time there! Would be great to see some pics! Need more XD's around here
What car setup are you running?
I reckon with the that motor, a longer runner, high rise intake will definitely pick you up some power. There used to be some data on comparison dyno runs with each of these manifolds, but I never managed to get a copy and can't seem to find it on the net.
IMO, the TFC looks like a great piece of kit and if I was in your shoes, I'd definitley swap over to one.
