Just want to let all you AZ WRX owners know that the guys at Dyno-Comp 2 in Scottsdale are probably one of the best WRX tuners in the state. They don't just sell the parts.. they install them, know a great deal about them, and support their work 100%! I just purchased the "new generation" BPM GT turbo-back( mine is fully polished and includes a high flow cat) and BPM uppipe from them. They were awsome in every aspect of the game. The install, the price, and overall customer service were top notch. Richard, the owner of Dyno-Comp does everything in his power to make sure that the customer is happy. Just two notes to add to this..they have the ONLY AWD dyno in AZ, and they are AZ's only authorized RENNTECH distributor. I'm sorry but if these guys can work on $100,000 plus cars, I'll let them tune mine anyday!
