hey Nic,
What dump/front pipe you got? xforce or standard?
Is your Apexi Pod exposed or enclosed in a box/heat shield?
Like you said yourself numbers on dyno MEAN NOTHING.. just take it down to the drag strip where it counts, one of the guys with only 169rwkw has ran a few runs at 13.7 with 19" rims while others with around 200rwkw can't barely break the 14 second mark,
so see how you go GOOD LUCK!
