I am looking at this programer on ebay. Claims more hp and mpg. Has anybody tried this or no of anybody who has.


PERFORMANCE CHIP CHEVY K 1500 1/2 TON TRUCK 4.3L V-6 1997 1998 1999 2000 01 02 | eBay


Im also adding a cold air intake and magnaflow cat-back exhaust will this effect this programer? Any insight would be appreciated.

Reminds me of the magnets that attach to the fuel line to magnetize the fuel that supposedly improve power and economy.
