What BHP is your clio running?

Either people on here use very generous rolling roads, or my engine is **** lol

179.9 at EFI on a dyno dynamics road
Air filter and suspected cat back.

At the same day a new 200 ran 187.something and an older 200 ran 174 iirc
 
Looks like the power is dipping and spiking all the way up the rev range :worried:
 
In most cases it's only the secondary Cat which is removed and in most cases the car will still pass without this being present. The main Cat is in the collector on the Manifold, it seems that this does the majority of the cleaning up and the secondary one under the car is just there as reinforcement. :smile:
