I have a 2021 wrx base, had the Stage 1+ Big SF Intake installed from Cobb. I know a Dyno is highly encouraged, but according to Cobb, the OTS is just fine. I don't race it, a little aggressive (85-90mph) on the freeway but that's it. Am I at risk for engine damage or should I be ok till I can afford the Dyno?
