UPDATE or NOT

[haffne]

Should I update my U7165 to R20? I have R17 right now and I am not having any problems with it, no codes, etc.... So should I update to R20 and if I do what changes can I expect?

Yes, fell free to update.
The new tunes are quite a bit better, and my roomates 06 picked up an extra MGP with 8r20 over 9r17, up to 17.5 mpg mixed driving from 13.5 stock.
If you do not like it, you can go back to 8r17, just always be SURE to restore the stock tune between updates.

Thanks
