Strange question regarding power

[jay5488]

So my XSI just lately seems down on power, are there any service items I've missed, done an oil and filter change, plugs and it's running a cone filter with cold air feed (normally better in this weather.... It's got some cams in and was really spritely before....
I've put a "6" exhaust manifold on could it need a remap after fitting this?? It's not rough or lumpy and ticks over really nice, no hesitation or flat spots just seems not to want to really go....

Cheers

Jamie

Blocked cat??

No, I've just,2 months ago, put one on....... Unless it's duff as I put it on the same time as the exhaust manifold.......

Thats so cruel.. take that cat out immediately! ;-)

On a serious note, if you really believe its down in power for just £30-40 your local rolling road company will provide you with the proof. Its amazing hiw much you can learn from just one visit.

My cat had fractured, shifted within the casing and partially blocked it.

Thankfully I don't have the cat problem anymore! :-)
