just wondering where my power has gone, produced 265.5 bhp at courtenay (where it was cs3 mapped) in november but only produced 211bhp at jam sport yesterday..
i have fitted a boost gauge and i must admit i turned up the actuator by a few threads....
is the actuator my problem???
i have set it back down now so about 5 threads are showing.
