I am officially through my break-in period, started the day with 875 miles and went on a 500 mile road trip. I'm debating whether to order myself a Cobb AP now, or wait a while. If you bought a new 2015-16 WRX AND installed an AP, how long did you wait, and why? If you could do it over again, would you have installed it sooner?
I installed the original AP-1 on my '05 Outback XT within a year of buying the car new and never looked back. Based on my positive experience with Stage 1 on that Outback, I'm tempted to order one right now and install it after an oil change, which will happen soon after I return home. I'll have ~2000 miles on the car at that time. The potential for a decided warranty claim is always in the back of my mind of course, but if something were to happen, I can afford the repairs.
Who am I kidding, once I've gone Stage 1 I'll probably mod a little more, perhaps Stage 2, TGV delete, perhaps both. (Cobb Surgeline is a short three hour trip from home... so getting proper Pro Tune is not a problem should I decide to go that route) I feel like it has plenty of passing power as-is but I want a little more "fun spirited driving" power and I'm hoping Stage 1 will smooth out the throttle response like it did on my old OBXT.
For those who installed an AP on a 2015-2016 WRX while still under warranty - how long did you wait, and if you could do it over again, would you do anything different?
