Fk7 feels slower after DP install

[Stupefyer]

Just installed an rv6 catless downpipe and my car seems slower than before. I have it paired with a Borla catback exhaust that I had for a couple weeks before installing the downpipe. No CEL or anything. Gonna reflash with ktuner and See how it feels. Anyone else experience this before?

It will probably get faster after you drive it for a while since the ECU will need to relearn the fuel trims.

I reset the ECU, then reflashed it with my Ktuner. Driven about ~75 miles and the car feels a lot better. Thanks.
