BrenTuning has tuned my 07 WRX twice with amazing results far exceeding my expectations. The one thing different about Brentuning is that the quality tune I get is done with pride, and not with just "another day another dollar" kind of attitude. I couldn't be happier with my car's performance and improved gas mileage. I've had my latest tune for well over a year now, still running strong. Very reliable, and safe for my turbo, but still 100+ awhp gains with just bolt-ons. If you're considering getting a tune, get one from BrenTuning. If you want to know more about my car, PM me!
