There was another thread but did not contain the info I need


I have a 04 WRX with Prodrives stage 3 reflash and other comp. ( dp ms ab, silicone everything, borla header) would getting an Access Port work and if so would it improve what I have...

Prodrive has possibly the most developed maps I have seen.

I really don't think that Cobb is going to have anything over Prodrive when it comes to mapping.

thank you
