a lot depends on the stealer, some are not as bad as others, not sure of newer cars but the apr single 93 octane program for my 2001 TT 225Q was a simple download, multi programs require a different APR chip, this install is a very delicate soldering job, with this install stock as well as 91,93, or 100 octane programs can be had alone or all at once

 

I had a Stage I flash done to my car yesterday looking to do downpipe and carbonio intake. I like the way it looks, not too concerned with lack of major performance upgrades

 

I have just the downpipe upgrade from APR for sale that will match up with your stock exhaust if you wanted to start there first. I was on a 2012 A4 quattro and had no runability issues with the APR chip either.

 

would people suggest waiting? my car has 120 miles on it..

 

Why are you getting rid of the down pipe?

 

Car is sold. Took all the aftermarket parts off. Wheels suspension downpipe

 

Just bought myself one of these... coolest **** ever Audi A5 with Motorized front plate - YouTube
