I can make my bone stock exhaust gurgle with a slight tip in and out of throttle at low speed.
Different exhausts make this more pronounced too.
I know J Dub is looking for an N55 sound and without a single turbo it won't ever sound like one. There are also slight internal differences of the N55 with cam phasing and stuff that to make it sound the way it does.
However, all that gurgle can be had with some slight changes into tuning.
The tuner in me says it's a waste of fuel and not the correct way of tuning though...
