Have the guys at Vishnu indicated what sort of power hike you could expect with the Meth, Procede and Test Pipe combo for an AU spec car?
I considered the Meth & Proceed option after reading the forum post here, but it seemed that as my car is stock, and running 98 fuel, the upside would be minimal.
From my understanding, the big power hikes were for the FI guys (lowered charge air temp), or those on crappy fuel (i.e the US guys, as the Meth effectivly bumps the octane rating up).
The test pipes on the other hand, I like. Im just looking for a 'no-cut' option.
