I need some help please,

If you have an airflow sensor and use this type of dump valve (vent to atmosphere) you may experience some overfuelling, is this a bad thing, i expect it is but am not sure as i know nothing about engines, could i stick another air pipe into the hose after the "MAF" that would at least add some air, i don't wish to blow my engine, thanks to any people that can help me & steer me the right path

(i will get some sort of dump valve).

This doesn't say if it's a twin piston valve... assume it is not & get a better one!

DV26 or DV36 are fine.

My DV36 is nice & loud, but for more cash (£100+) you can get demons that live under the hood!

Cheap & nasty will fail sooner than a well known brand!

It wont work on your car as its a single piston. It will just create a massive boost leak.

Yep, stall is what you will get.... about every 10 seconds!

Any twin piston will work, but the bailey is a good shout & loads of ppl on here will agree that they work well!

Other big manufacturers also make good ones.

I'm about to switch to a DD Blitz BOV. They actually have a whistle built into the exhaust!

If it's not loud, I'll die of shock!
