So with 8 new plugs and 8 new coils, the LS8 is running great and sounding better than ever.
I figured I'd try to get a wind-free recording of the exhaust note under normal driving. Took my old android phone, started up a sound recorder, wrapped it in cloth, and fastened it to the backside of the rear bumper. Great theory...the recording was wind-free.
Unfortunately, my old phone's mic picks up exactly -300% bass. So the recording sounds tinny and rattly, like a race-tuned hemi (real Hemi, not the modern garbage). Doesn't sound anything like the actual car. My new phone's mic picks up bass just fine, but I'm not about to strap it to my bumper and go for a drive.
