has anyone hot one of these bmc cda filters fitted?? if so are they hard to fit and are they worth £200?

the way i look at it is.. i paid £200 for a remap that gave me like 50 bhp more and a buvket load of torque... is that the next step or should i go exhaust with turbo cat back?

? help lol what do i do next boys?? had the map done last week lovin it but want more!!! lol im running on 197bhp 215 ft per LB.. other than a forge 007p and remap is completely stock.. but also on the remap report under advice on the back i have a weak actuator and a damp pcv system what ever that is??? :-/ so where do i go next?

?
