if I buy a procharger for my 2012 SRT, I know tuning is required. But if I take it to a local dyno and have it dyno tuned, will I even need my own diablo at all after that? I mean once its dyno tuned, its done for life, right?

You will still need your Diablo tuner that is how the tune is loaded to the car, The tuner will use your handheld to get the job done.

You have 2 options,

1) A professional dyno tune that replaces your stock tune with a custom one.
2) A handheld that STORES the stock tune and put in a semi-custom one.

#1 is generally the best BUT, if you ever take your car in to a dealer and they reflash it, your tune is TOAST unless your tuner keeps it and reflashed your old tune back.

The handheld, you can restore the stock tune yourself, take it in for whatever and then put your own tune back in.

You will need a safe SC tune to even start it once the SC is installed (not WOT, just safe partial throttle timing and A/Fs). Then have the WOT parameters tweaked for highest efficiency on the rollers to ensure you don’t run out of fuel pump and cause a lean condition. You will need a tuner to do both.

Getting the safe everyday driving tune is the important one IMO. You can always prevent WOT but you can't prevent partial throttle.
I think you'll find the tuner handy as not knowing what your traction issues may be, you'll probably want to change the rear tires and may need to change your tire diameters or your fan settings.
Are you planning on more than 6 Lbs of boost? May want to consider pistons as the stockers have been breaking ring lands like crazy in the hot south.
Dropping the CR to under 10:1 and running pistons with >.040" distance from top ring to piston top seems to be the way to get the most power (boost) out of the 6.4s.

I plan on getting a d1 head, but only running 6lbs on current engine. I work at a junkyard so im looking for a 392 block. Once I find one, ill build it up forged for lots of boost. I reckon ill get the diablo with the prokit and still may upgrade to a trinity after fact.

Even with a Dyno tune you still need to have a handheld!
