Hi I've got a mk4 gti turbo. It's got the tt turbo. It's came with a none-resurculating  dump valve. I want to replace it with a resurculating as I herd a none-resurculating one will mess up the fuleing?????? But what do a buy it for a tt or a golf ?????

The Forge 007p/008p fits both and is the preferred choice.

For anyone that cares ive beem running a baileys dump valve on my agu for nearly a month now with no drop in fuel consumption no loss in throttle responce and no engine problems. Infact i think the forge was dumping red hot ait into my intake. If u have a agu running a dump valve will. only make noise not cause problems

You wont get any EML problems with the AGU, on the other hand on the later 1.8t's i.e BAM, AUM, APK ect you will. They have many more sensors and are more sensitive to drops in pressures.

This is the same thing my mate was talking to me about last night. His mate has a vrs with the auq or aum engine? Well he said the recirc valve just dumps hot air back into the intake, so he has stuck a racing one (dont remember the name) he also said he has noticed a difference in performance (better now)
He also said it aint caused any probs and has ran it on a good few vags now and never had a problem.

Aparantly on cars without a MAF a recirc valve is purely for noise and emitions. Tbh i cant feel no difference in power between the forge and atmospheric dv on my car

Whys it called the cold side as its dumping it into the inlet still. I would leave it standard and let the oil cooler (intercooler) sort it out.  :grin: Also the air its letting out of the dv is what goes through the engine, hows it get hotter coming out of the dv . Sorry had a few beers and can not work out the cold side thin making any difference if you can under stand what im on about.  :embarrassed:

Is you agu mapped? I ran forge split r on my mapped agu and i clearly felt slight boost loss due to it. Changed it to a 007p and was ace..when car was standard never noticed the boost loss. Yh it will not throw fault codes but its defo no where as good as a 007p  :wink:
