All booked in for Cp340 map at the end of the month, with all the required hardware taking it to Cp370. What would be the best to use between the mountune airbox with a k&n extreme filter, or ditching the airbox and getting a bigger Group A? Thanks :)

I think the difference in power is a bit of a myth if you look at the science of induction so as long as the car can take in the air it requires for the map etc all is well.

But it has to be Mountune of course. Why? Because it has to be lol!

One of my mates had, along with other hardware, an AS CAIS, made 430bhp swapped to a Group A, and struggled to make 400 on the same rollers
I understand, but logically it's hard to grasp how two sports induction systems both designed to improve airflow can have a difference in power of 30 BHP unless other factors are involved?

Ambient temps will have played a part, the Group A will suffer on the rollers as well due to engine heat soak.

Personally, i've got a AS CAIS and won't be going for anything different :thumbsup:
