Recently my car has been feeling like it has turbo lag (not a turbo though, lol) could this be a vacuum line? also felt like a knocking noise was happening a few times but havent heard it since. Any ideas people?

When was it last serviced? Does a diagnostic fault code check turn anything up? What fuel are you using?

Was serviced about 6 weeks ago but recently got a new highflow cat put on it so could it be a leak there??? No Faults when serviced and no lights showing up at the moment. Usinf V-POwer which if memory serves is 98 octane, so the best fuel available at the pumps.

Think its a leak in my exhaust when they welded it up they missed a spot so that may explain the loss of power. thought it would happen as soon as i got it back but over the 2 weeks maybe a sharp jolt or something cracked a weak point in the weld.

So the clunking noise could also be the brakes? even if it really only happens when not braking??? i will ask my mechanic to check the brakes for me on Monday :) Thanks.
