Hey everyone! I just bought a 2015 A4 and I'm looking to chip it to add some gitty-up to it. I've heard I might have to gap my plugs down from stock .032" to .028" and upgrade the diverter valve as well? Is this true? About how much will everything run me, and I've heard there's a lot of chip options out there, but don't know where to start, or which would be the best one. HAAALP! Please and thank you!
