AU II XR8...Need More Power...Advice?

[ThoR_]

Im looking to get more power out of my AU II XR8 Auto...I have an 2.5 exhaust which has gained a bit.....I have a K&N Panel filter with the Tickford snorkel aswell....Could i mod the airbox more? Or get a pod and ditch the panel filter?

I will eventually get extractors....After that though...without taking the engine apart....whats the go? A performance chip?

Also...I got told not to bother shift kitting a Adaptive Shift Auto.....Is this true? Because i never thrash it enough to get the gear box to turn to harder shifting.....Is it worth it or will they just damage my gearbox?

Also it does clunk into 1st if i frop it into it under 40kph...Is this normal?

Cheers
