I've heard a lot about the 710n DV for mildly tuned engines, but should I go higher than that? Ill be adding a frakenturbo in the spring, it's currently stage 2 performance tuned, chipped, performance exhaust, and other stuff. So 710n or something else? (I'm assuming my DV is on its way out or will be soon with 188k on the original DV)

 

Do you have a boost gauge? How much boost are you running? A 710n is good for about 15psi. Anything more than that and you should really be running a piston-style DV with a spring specific for the range of boost you're running.

 

I do not have a boost gauge and I have no clue how much boost I'm running (not to spun like an idiot but I have no idea how to find how much boost, nor do I know exactly what boost is)

 

Boost is what the turbo makes,(to increase the induction pressure of (an internal-combustion engine) above that of the ambient pressure), and a boost gauge is what you use to measure it. ( a pressure gauge that indicates manifold air pressure or turbocharger or supercharger boost pressure in an internal combustion engine. They are commonly mounted on the dashboard, on the driver's side pillar, or in a radio slot. A boost gauge will measure pressure in either psi or bar; many also measure manifold vacuum pressure in inches of mercury (in. Hg) or mm of mercury (mm Hg).)

 

A 710N should be absolutely fine.

You are just chipped. You can't be pushing too much boost.

FWIW, "Stage 2 Performance Tuning" == being "Chipped."

How do you know you are chipped if you don't have a boost gauge?

 

I'd also have to say that if you're chipped, then your DV is likely upgraded already. A stock DV won't hold aftermarket boost levels.

 

It's very possible It's already been upgraded as I bought it about 6 months ago, can I look under the car and tell if its been upgraded or not by the writing on it or something?

 

yea it wont have stock part numbers nor say audi on it

 

If it's a 710n it will....

 

just take out the passanger side headlight and dig around under there. you'll be able to find it if you at least kind of know what your looking for. and its no promise its been upgraded already. i ran my stock diverter valve for 30k miles and it never failed on a chipped ecu
