Here are 2 quick videos. I'm kinda limited on space to let it rip in town I'm in. The in car represents the sound the best. In the exterior video the drive away sounds raspy for some reason and it's not in person. The revs are accurate. The corsa with spd has a much smoother even balanced sound vs the corsa res delete. This setup is aggressive though.it is not quiet once in boost. Cruising it is fine. There is more cabin noise with the spd. I wouldn't say it's drone but you can hear it more in cabin around 2k. Overall I think it is very close to the gtr sound. I never wanted this truck to sound like a v8. I wanted to capture the turbo v6 sound.
