I'll chime in, too. Have an 08 STI. Got tuned shortly after purchasing @ 60k miles. I've put 14k miles on the car in 6 months and it has never once hesitated or given me any trouble at all. Currently Stage 1 w/ no mods. Made ~300whp/350wtq on his dynopack. Night and day difference over stock. Bren has also been great about answering questions I have had on parts, maintenance, and general subaru stuff. I wouldn't bring my car anywhere else. Thanks Bren!
