You're right W, POWERCHIP is located in Santa Monica, so I just took my car over to 'em. They pulled the board out ( much like a computer board )
by sliding/pulling the 2 tabs that hold the board in place, did their voodoo number upstairs in their offices, and slipped the board right back in. Took 30 minutes top. Too bad they don't have reps around the country as UPSOLUTE does. Even more of an incentive to lower their prices. Still, for me, it is a worthwhile upgrade. When I took my XFIRE into the shop for the first oil change, the dude who drove my car said it felt more peppier than the othe XFIREs he had driven. I didn't tell him about the upgrade. For me, its a need to know basis, and the dealer don't need to know. But the extra horsies sure come into play when driving on the freeway to bypass those clogs that occur now and then. We both agree, I believe, that the software upgrade ( POWERCHIP/UPSOLUTE ) is the best thing we could do to get the max enjoyment from our XFIRE's.
