i've got an cobb ap v2 for my 06 wrx, would it go through 08 sti?

 

different part number. most likely not

 

so mind as well get v2 for 08 n sell the other ap

 

NO. It's better to sell your ap you have and go open source.

This x2

a 08 just got tuned with us and made 291 awhp/ 328 awtq on a safe tune (catted dp and cat back exhaust only)...... unlike our other suby friend who was tuned by someone else with his cobb and was pulling -9 timing to have good #'s then he got tuned and gt just about the same #'s on a open source tune but his car is now safer and feels stronger now

 

hmmm...

 

Perry a lot of us are open source now so there's a bunch of people you could talk to about it. Also there's loads of info on the internet.
