lack of boost after fitting exhaust

[inde_house]

So I have had some exhaust changes done. Standard downpipe with decat and a bsr cat back system.

But now the boost is much less then it was. I dont have a boost gauge. But standard gauge on the dash barely gets into white area.

Any ideas.......

I checked the vac lines and they all seem to be connected. And they were not long replaced.

could possible be down to less back pressure with you removing the cat and having a bigger bore zorst the best thing to have is a boost gauge to be able to monitor every thing correctly

Nice one james. Will do that. Definitely feels nicer to drive. Definitely more eager to boost.

Any one else has problems like this after fitting and uprated exhaust
