2011 Crown Victoria Police Interceptor Mods?

I own a 2011 Ford Crown Victoria Police Interceptor with a 6.4L V8 and 84000 miles. I want to know how to increase as much horsepower as power and upgraded performance as possible within a $1000 budget. I would preferably like to use performance chips and modules but I'm not sure which one will work, especial for the "best bang for my buck". I would preferably like to push in an extra 65-100hp.

Is the Ford Pinto really a deathtrap?

I heard that the fuel tank would 'detonate' if you got rear ended. Is this true? Was the car any good at all? They don't have the Pinto here in Britain but my dad used to drive one when he was still in the States. If what I've heard is true, I'm guessing he's lucky to be alive.
