In case anyone was interested, I read over at the forums at upsolute.com that the US dealers are having a $75 off sale for the Holidays

Has anyone used upsolute chip tuning on there cars? ANy feed back would be helpful.

I might be the only cl/w203 owner here who's done it. I had mine done, bookended with dynos. That same day, the topend gain was only 6hp; however, the computer does need time to adjust everything. My buttdyno says that I've picked up some additional ponies since then.

I had the car re-dynoed this past summer, and it showed additional gains, but then there's the different dyno/day, etc. factors.

To sum up, though, for the money, it's ok. But there are other hp-gaining mods that I'd do first.

Such as what (for an '05 C230K SS)?

Looks like those clowns will never get around to updating the REAL horsepower gains (or lack thereof) for the C230 coupe:

Borders on fraud if you ask me.

Jim, I'd get a new exhaust; my car felt much better after my Eisenmann was installed. Also, wait for the new pulley(ies) to come out for the 05s before experimenting with ecu programming; hp gains are much higher, and you'd have to get the ecu reprogrammed after getting the pulley anyway if you had the ecu done first.

Good to see that oggle still can't get over Upsolute's screw-up on their website.

Haha I would get over it, but don't you think them not correcting it for this long borders on negligence, if not outright fraud? I mean, they've been made aware of it for the longest time.

Tommy, thanks for your feed back. I am looking for more throttle reaction time. Can you tell me about that?
