Bypassed N75

[ntails]

I've only just noticed that my N75 valve has been bypassed by the previous owner at some stage. Has anyone here done this on there car?
There are few guys on vortex doing this to fix boost surging.

And put what in place???? N75 is the boost controller valve and has a duty cycle controlled by the ecu and wouldnt mess with it unless you are using an alternative controller adjusted correctly, unless you want a ticking bomb in the engine bay.

Do you perhaps mean the N249 valve which controls the wastegate, and can be bypassed to help control surging? I can't see how the car would run for long with the N75 completely out of the loop.

Sometimes replacing the N75 with the N75J version also softens the surge a bit - I've done this on a Polo.

The N249 controls DV , the N75 controls wastegate

You're right - my mistake.

The N75 is still plugged in, just the hose is looped back on itself. There is a MBC in its place, which i am assuming was put in when the car was chipped, once again by the previous owner.
Max boost is ~12psi.

So with the MBC it is ok to have the N75 bypassed?

[fuzion]

if the car was 12psi it was definitely not chipped.

it was put in place to try do the dodge and get more boost, its not good for the car and no increase will come out of it imo.. go j or h valve and get a chip and you will get the performance change what you'd be wanting..

[ntails]

Is there anyway to confirm if the car has been chipped or not?

How well the car goes, boost gauge on it to check what your getting prob the easiest

you can tell a stock gti vs a chipped gti .. stock gti = hyundai getz lol

I watched the Top Gear Episode recently where they race a stock Mk4 GTI against a diesel Skoda Octavia and another car (a frenchie IIRC) - and the GTI comes stone, motherless last.

They then drive the Mk5 GTI and it's all smiles, sunshine and rainbows again.
