With an SLP CAI is the PCM located inside the CAI box (like with a stock box) or do I need to buy a PCM tray? I know the Thrasher CAI comes with a poly carbonate tray but it looks like the SLP holds the PCM inside. Thanks.

it's located inside the airbox, you might want to get some velcro or zip ties to secure the pcm in the airbox.

So it doesn't fasten inside the box like stock? Will the velcro keep it from bouncing around?

to some degree i'ld assume, never liked the velcro idea unless it was in an already tight area. but you can just drill a couple of small holes and run the zip tie through it and that'll hold it in place pretty good.

Thanks. Will try that. Don't want the PCM bouncing around. I've found that vibration and electronic devices don't mix well.
