Hello all, I'm new here. Duh, it's the new member hangout, where else? I do, however, have questions for all you here that have been where I'm trying to go. I have a 03 wagon that I bought new for my wife, the only change from stock is an AEM intake. She wanted something with a little plusher ride, so she now is driving a Volvo S-40 T-5 turbo. I had to take over driving the WRX. Tough job, but someone had to do it. I'm looking to get a few more ponies out of the stock engine without major changes, and I figured the ecm would be the first place to look. What is the favorite vendor or supplier for an upgrade with all you more experienced guys? Do you have any ideas that might be a better place to start?
