I just bought a 2003 996tt and I am interested in ECU tuning. Has anyone used the 'Upsolute' company for their tuning? They claim up to 100hp gains on my car and their pricing seems very reasonable. Do you recommend any other ECU tuning companies or is it a bad idea to begin with?

Thanks.

 

I am not a fan of upsolute tuning, but it is definitely a cheaper alternative. In my opinion, you get what you pay for, and they have had numerous problems in the past with ABS and CEL lights. Whether that has been fixed by now (i would hope so), I don't know. I use GIAC software, and we get 75hp/78tq out of the flash. There are pros and cons to every software program out there, do your research, and go with the one that is the most solid.
