hiya

the standard setup is already very good, the only way to see decent gains is to switch to 2 vernier pulleys and move on to throttle bodies. Mine made 210bhp with Jenveys and fixed timing, most tuners wont go near the VCT as apparantly its a nightmare to map.

Originally i had a K&N filter, mongoose exhaust, vernier on the exhaust side, and a remap and it made 183bhp @ 7300rpm ish.

Hope this helps

Dave
