olstyn- Yes I have APR stage 2 since I have a full turboback exhaust. Wait til around Xmas time and APR will usually do a special on a fully loaded ECU for $500 which is the normal price for 1 program and stock. I was able to get a 91 tune, a 93 tune, a 100 tune, valet, and stock for $500. The DV I went with was a Forge Splitter. It is the best of both worlds. And as far as boost gauges go, I am running a Prosport gauge. You can get a mechanical one for roughly 40 bucks, and if your car has the blue/red gauges, it matches almost perfectly. If you have any questions, shoot me a pm.
