I can't believe I read this whole thread.
If you want power, go turbo or swap. If you want NA KA, don't expect much.
It has been beeten to death, to make sr power on a reliable na ka, you will spend upwards of 5k. I run injen intake, Greddy headers, flowmaster cat, custom 2.5 exhaust, nismo flywheel and I make 156hp and 164tq to the wheels. a tune might gain another few hp, but not worth the money. I understand the ka and accept the fact that it has na limitations. so should all of you.
