1995 Subaru Impreza Wagon

[rivman05]

Hi, I have a 1995 Subaru Impreza Wagon. It has a 2.2, with a 4EAT for engine and transmission. I have an intake, and soon to get headers, high flow cat, and mid pipe, and a new axle back. I have an issue tho, I have been told that to take real advantage of all of it, I would need to re-trim the MAF signal, and a few other things. I could do this using RomRaider if there was a version for older Scoobs. Now this being said, I also have cams ready to go to Delta for regrinding, and have ported and polished heads. I am curios what are peoples ideas about what to do, should I buy EMS from someone, or can I reflash this ECU? Just wanted to bounce this around since I cant hardly find parts for this car, and need advice and help.Thanks guys, appreciate anything that can help me one way or another.
