Hey guys i have a 2004 A6 S-Line, and i just want to know, which Diverter Valves do you guys like for the 2.7, forge,apr......ect
and also , is it true the forge/lltek BOV isn't good for the car?? Thanks alot.

 

You can go with Hyperboost, Forge, Baileys, 710N's. I would hold off on the APR R1, they were having issues with them on the 2.7T cars with a constant honking noise. I am not sure if it has been corrected. As far as the Lltek version, it is a hybrid that combines both recirculation and venting into atmosphere, they have no benefit for our cars, all they provide is the "whoosh" noise of the venting and the cost is thru the roof!

I have the Hyperboost and my brother in law has the Forge 007 on his S4. They work extremely well and you can service them.

Hope this helps!

OOOO

 

Yeah man that helped, thanks alot!

 

I bought some 710n's for the price, the pair was about half of one baileys valve, but they work great. I know I cant clean them, but even if I go through I know I saved a few bucks. Also I heard they work fine even with Ko4's, and I really hate the "woosh" noise of my friends s4 (forge 007) Don't get me wrong its a nice noise and it adds to the driving experiance, but you could hear it over the radio and this is my Daily Driver, I just though it would get old!

 

thanks, but what i keep hearing around the forums that BOV or rather Hybrid DV's / BOV's hurt your gas milage and hurts the motor as well, down the road, is this true??? and if it isn't which BOV do you like the best, forge??, thanks again?

 

oh and trapped, i forgot the ask you, how do you like your APR chip, can you tell a diff in power...ect, and is it pretty smooth??? thanks.

 

YES its wierd because it does not feel any diffrent, you really don't get slammed back in the seat. There is much more speed. I don't know exacly how to explaine it, but yes its faster especially in TIP mode. I used to hate driving in TIP, but now I love reving it to about 4000 and getting that added boost. At high revs in 2nd if you floor it you will get slammed back and easily hit 60 in a second or so. I kinda wish I bought GIAC to be honest, but my shop could do the APR in 20 mins through a VAG. Anway if your not chiped do it! Its well worth it.

 

thanks, i deff am, i was either looking at GIAC, APR or GMG, im not sure yet

 

I think if I had to do it again I would go with GIAC, I think it would be worth the wait of sending off the ECU

 

GIAC is the way to go i have it ... its very aggressive ... BOVs hurt audis ... i guess those hybrid ones would be ok if you were looking for that obnoxious sound ... but otherwise i run the bailys and they are nice ... the 710s are def a cost effective way to go aswell...
