Default Z06 H/C/I Diesels on shutdown

2007 Z06 with H/C/I. Mods are listed below. Anyone here experience dieseling when they shut the engine off? It diesels a bit before finally shutting down and I'm almost sure it can be changed in the tune.If I blip the throttle a little bit and hit off it shuts down much smoother. My tuner did a great job with all the rest of the tune, I just forgot to mention to him about the dieseling issue. Just looking for some feedback and possibly if anyone knows what needs adjustment to correct this. Thanks for any info

Mine does it with a BTR stage 3 cam. Switching to iridium plugs helped a little.

I've heard that switching to a 2010+ ECU will fix it.

Me and a buddy got it all sorted by enabling VE and MAF and playing with injector timing. took about 6 calibration pushes to get it dialed in. All good now!
