MG ZR: Cams & Maps

What about a blocked cat or a shit air filter?

Cat and lambda sensors were replaced a lil while back at great expense to the previous owner -see page 8
Air filter is k&n enclosed, although the caf isn't on it since it kind of got broken off to replace the radiator. Garage gave me some air ducting pipe stuff to make up a feed but it wouldn't cost me that much power?
Besides the garage took it off and ran no filter just inlet pipe facing the fan for a run to see if it was restricting it. Pulled the same number

So basically you have bought a f*cked one?

Starting to seem that way, the more and more I hunt for dyno results the more I'm certain 140 isn't right. For example

"at the first MERSEYSIDE DYNO DAY we had a 120 and a 160, both with CAT back stainless exhausts, K&N Air Filters and well maintained, 160 was 159 and the 120 was 120.2." The 160 was apparently 28k on the clock and apparently the cat back systems on these are pretty much empty/unrestrictive as standard. Although the first car pulls 160 with manifold and remap

I understand dynos arnt perfect but their graphs show power right up the limiter whereas mine at 6.5k just go flat

Midnight I have no idea either, it could be something really stupid like a oil sensor stopping vvc working or a leaky gasket I just dont know where next to look without wasting money replacing/breaking everything

It was first dyno'd at autotronix in sheffield along with alot of members on here
http://306oc.co.uk/forum/thread-18008.ht...lling+road It's says 150 but that's corrected number
Second time was at RStuning in leeds with their big super duper dyno dynamics one
