Cool, so technically, I can run it off the laptop all the time if I really wanted? (I dont want to, that would be a fun "look what I can do" type thing). lol

I did forget to ask a very important question.
Will this chip function for me?

I found the adapter, I forgot to verify which chip I need, I do not want to reflash the stock chip due to keeping a backup.
Plus, I dont think the stock chip can be reflashed even if I wanted to.

Yah, I have been reading them for a while.
I have an idea of what things should be based on what I read but I'm still lost on a few things, but I have no experience with doing this yet.
Its like chopping a tree down with an axe, you watch videos and know how it should be done, but when you try it yourself, it doesn't work to well because you do not have any practice or experience on exactly how it should be done.

Basically, I have to learn by trying it, thats why it seems like I am jumping right into this.

go to w-body.com and find the member "turbo v-sick" his name is Adam and he will set you up with a tune for your car!
