I'm looking to purchase the Flyin' Miata - Hydra Nemesis ECU Upgrage for my MSM and was looking for a good reputable shop that could effectively do the tuning without blowing my car up. I've heard good things about Mainstream Performance but was wondering who you guys would trust. This is a full ECU replacement that comes with a basemap. It comes with a built in boost controller, eliminates the MAF, and would more than likely require some A/F Ratio tuning on a dyno-tune. Also looking to upgrade to 550cc injectors at the same time. If I could do this stuff myself then I would, but at this point in time, my tuning abilities are limited to what I can do with wrenches.

Thanks guys.
