The guys who did mine (Porsche Pitstop, Alexandria VA) highly recommended the Upsolute chip vs. any of the other chiptuning they offer. By far the best bang for the buck. They do mostly Porsche's (hence the name) and VW's, but also quite a bit of Mercedes work. It was their opinion (and trust me, I asked, since they offered several different chiptuning's) before I made my final decision to go for it. They'd have made more money if I'd bought one of the others, so in my book that tells me they believe in value of the Upsolute. But hey, if there was only one opinion out there there'd only be one chip, eh? I would not personally discount or lend higher credence to one opinion vs. another, nor would I fault anyone their selection (to each his own...).

As for the problems BobaFett's having, well, what can I say? He's done a lot of mods to his car already, not uncommon for highly mod'd cars to have problems in interrelation of the various mods. Hopefully we'll hear soon his resolution. Maybe the Upsolute chip just work's on Alabaster's :?: 8) :?: :lol:
