Stock cat! Bin it. I had a 2yr old 3" Catco and it was hurting my power to the tune of 15-20rwkws. So the std cat will be killing you. Have a graph? Curious to know how the P25 exhaust housing goes

[rad100]

will get one up now!

Who tuned it? The eboost looks like it needs lots of work! Hits 11psi at a reasonable rev then creeps up to 14psi. All things considered it looks more like a boost control problem, but if you drop the exhaust inc the cat it will be a good cheap test of whether the std cat is killing power like you would expect.

But yeh, boost control needs work, dump the exhaust and then ask the tuner why is it only making the power it is ...that is of course after you have replaced the AFM

[rad100]

yeh gonna drop the exhaust on sat, then wack a z32 and a bleedvalve to c how it runs then! the eboost is just poo fullstop!

yeah get rid of the cat ya will see a nice gain out of it and try a z32 airflow meter that will help as well
