these guys advertise they can get the 550is horsepower up to 387 from 367 and torque to 520nm from 490nm.

and these guys advertise they can get the 550is hp from 367 to 405 HP JUST FROM A CHIP TUNE!! and the torque from 361 to 398 lb/ft.
Does anyone have any idea if these numbers are legit.

I've heard of both brands and they're very popular in Europe. Upsolute was relatively cheap when I first looked at them back in 2005 or so for my 545. That said, I don't recall reading about any independent tests of either tunes. There are some on here that have Upsolute and DMS software on their car so hopefully they'll chime in.

I doubt it...The tune I had only yielded about 7-10 hp at most....It is very hard to squeeze extra power out of a NA motor...The factory does a very good job tuning these vehicles....I would not waste the money on it because you will hardly feel the difference...If you had a FI car then it would be another story...A FI car with a tune should be able to pull around 50-100 hp no problem! For the money I spent on a tune, I wish I would have just saved it!
