The compression ratio is way to high on the 2009 hemi to be taking forced air. You are either are going to have to make some modifications or go to racing fuel.

Why is it you can add a super charger to an '09 Challenger with the Hemi and 10.5 to 1 CR but you can't add it to the RAM with the same 10.5 to 1 CR? Even the 6.1L has 10.3 to 1 and I'm seeing them blown.

same thought this way, will keep waiting for an update...
I know 10.5 to 1 seems a bit high for a boosted engine but we're only talking 5 or 6 Psi. It seems we'd be hearing of a lot of issues with the Challenger and Charger if it was a big problem. And for some reason, I don't think these people are driving around with 110 octane fuel.
Someone please post a link to proof of engine failure due to the new Hemis having a power adder and 10+ compression.

MDS, pretty sure mine has never gone into that. I do not have the indicator but I can hear and feel my engine. Old gear head here.
I think you might be mistaken by this comment. You absolutely CANT feel when the MDS system is active. It only kicks in when you are cruising under easy loads (Cruising speeds on easy terrain and also when slowing down slowly)
You won't feel any power difference and you won't feel anything different for the truck motor such as vibration differences as it continues to run all 8 cyls...only 4 fire. If you have MDS you probably have had it happen quite a bit. In all honestly the light really bugs the crap outta me...as I try to drive to keep it on.

Meth injection would be a nice adder.....and do the job.
