Power gains ??

What power gains do i get from removing the N249 Valve?

I couldnt say i noticed any power gain.

But the DV response has been much improved.

Probably sound stupid here but im not a machanic

What do you need to do to remove it? do you need to buy anything ??

Whats it meant to do when you remove it??

 

[Simon L]

You'll need a Y or T piece from B&Q for the piping.Also some vac piping from samco or silicon hoses.

This by passes a valve and reservoir that are used by the ECU to open/close the DV on demand. So even when you are full throttle, if the ECU wants it can open the DV and vent boost.

Bypassing these stops this, and also speeds up the time time it takes for the DV to open, vent boost and close again.

if in doubt, don't do it

but it's so simple & easy - if you can't do it, you must have velcro shoes since shoe laces are harder to tie.

print it off, and stand with it infront of you engine.

lol, will do that

How long does it take?

 

[Simon L]

Near the last couple of pages theres a simple explanation of what needs doing.

If you have all the bits you need infront of you, about 5 minutes.
