MK used to make a plug in maximizer that consisted of a dial on a black box and you plugged the TM into it and the maximizer to the battery. Worked good, but out of production by about 10 or so years. Do see 'em on occassion on swap/sell boards around and on Ebay.

That's be about the only way if you're a mere mortal and Pole ain't your last name and Cane ain't your first.
