now i have my new astra i (after reading here) have decided to look at options available to tune my car to get some more power
i know its diesel and as such should be slow and smoky but you know what it is like when you get used to how much power you have (you want more).
i have read about boxes you attach to the engine but am not sure if they are any good or are just a scam. i have also read that i can get the software upgraded but again not sure if it is any good.
can any of you give me more information on what is available to me and were to get it?
