Cobb AP and Catless dp
Hello, I recently bought an 05 wrx a couple of months ago. Now I bought the car completely stock except for an aftermarket perrin downpipe.
Now I was having some trouble trying to figure out which DP i had exactly, but I've figured its a perrin catless dwg, perrin dosent make them any more. Ive included some pictures just in case I am wrong.
Anyways, when I bought the car I assumed it was tuned for the dp, but I realized the guy never told me if it was or not. (The car has been running fine so far) I tried emailing/calling but never got a response.
I was thinking of buying a v2 ap, but I've heard issues about boost creep with a catless dp.
SO I was thinking of running this, please tell me if it's a horrible idea and if I will break my car: 91 octane stage 2, then datalog, if i'm exceeding boost then 91 octane stage 2 LWG.
My area has 93 octane but I'd rather choose 91 to be safe. Also, is stage 2 alright even though my exhaust is stock? To be honest I'm not looking for that much more power, I just want my car to run better.
thanks! sorry if tldr.
