Hi i have a Audi A4 1.8t i'm planning on buying a boost controller and a DV/Bov? I was wondering if anybody has recomendations on brands i read alot about LLatek Dv/Bov and the GBS Stealth and the Greddy SBOV? any gains in HP with certain ones? any reviews?
Also how much do you think i can boost with a stock setup and Dv/Bov?thx for any positive comments i'm new to the AUDI game....

 

yes you are new. anyways read A4 forum first before you make a new. You need a DV.

NO BOV

You need to get a chip, no boost controler. "93 octane" chip is a good start in the road of tuning.

and again READ A4 FORUM FIRST THERE IS ALL THE ANSWERS

 

i love newbs.... DO NOT GET A BOV IF YOUR CAR IS NOT TUNED OR DOESNT HAVE THE SOFTWARE TO RUN IT... searching is a good because 9 times out of 10 that topic has already been covered.. I dont mean to be harsh its just a common question that many ppl ask and ALWAYS get the same answer... as for the stealth many peeps have ran it with no problems reason being its a hybrid very diffrent from a standard bov has a valve so you can tune the air to be recirculated.. you will not gain any power from a dv or hybrid bov just regain the power you lost with you stock pos one

 

There is no power gain from a DV over a BOV. All a DV does is help reduce turbo lag not boost your power. You can get a boost controller if you wish but you will also have to get an afc, piggyback system or a SFMS. As far as BOV you have to tune your car so that it will not run rich when the air is vented, not hard to do but many hours of work.
