on my octavia vrs when i floor it i get a bit of clitch just over 3000 rpm and then power comes back. it seems to dump k but at times don't feel as quick as i think it should be. anyone any ideas.have replaced the funny y shape pipe as went soft and will be cleaning dump valve out later. i've not got a boost gauge yet so not sure if pressure is dropping any one any ideas plz help

Could be coilpacks/plugs under load.

You need a fault scan.

I know the feeling,

I replaced the crank breather pipe, and the intake manifold pipe as they were both split,since I've done this the flat spots have gone when under load on the turbo but the power seems to fade off after 3-3500.

I'm getting a boost gauge.

Would a vag com show up anything untoward even tho i haven't got engine managment light on.

Maybe in expecting to much from this car but u can feel the boost kicking in but seems to fade off
