So I bought a cold air intake from protuninglab, installed it and then get a check engine light. I noticed a decrease in power but as I drove on it, it would subtly get better. I next reset my ECU by unplugging my negative terminal for a bit and tried the break pressing too. I noticed a much better sound of the intake sucking air and it has much better power than when I first installed it. I notice when I floor it the rpms shoot but there’s not much push or increase of speed when the stock intake was more responsive (this fluctuates and sometimes I do speed up well and someone do not, probably something with gearing) Check engine light is no longer appearing but the power is still not 100%. It is also notably a little laggy I guess you can say when accelerating from 0 then it kicks in at once. This is a 2015 2.5 L GT s. Any ideas on what could be wrong?
