Alright so I have an 07 a4 2.0t quattro and I am planning on going stage 2 with it but I have not done anything yet. I have read many forums about needing a dv when you get an ecu and all that but I really havent heard much as for what exactly i would need to run stage 2. My plan is to get an REVO ecu, and Evo CAI, a revision D stock diverter valve, and an APR exhaust that comes with a downpipe and there is an optional test pipe that goes with it that I plan to get with it. Would that work to run stage 2? Or would i need something else or does anyone have any suggestions?

 

That will be fine for stage 2.

 

All you need is the DV, PCV fix, Downpipe or Testpipe. You can do Downpipe / Testpipe only really but the other 2 may blow out at anytime. Ebay has very cheap testpipes and this could save you a ton of cash. When I did my DV it was ripped and I had unknown power loss.

Trust me.

 

i did the same thing. Revo Stage 2, forge DV w spacer, PCV fix (BSH makes a good one for about $100), 034 motorsport HFC, Stasis exhaust, also you may want to replace the hose on your intake (not the intake box). 034 motorsport makes a good one and helps air get in fast than stock (a little better response), also i have a K&N as well. It sure adds a lot of fun to your car.

Be careful with the test pipe cause it will most likely stink and you may not pass emissions if you get a notice. If you have the money go with a HFC.

enjoy

 

I am catless but my state has no emissions. More power from a testpipe and yes a little smelly. If you live in an emmission state get a High Flow Cat for sure.
