I would go with UTEC cause there are 2 tuners that I know of in the area. EcuTek is cool but if you're looking for the most power out of your setup I think UTEC would be better, but of course Standalone>Piggyback. So if you've got the funds go Microtech or AEM. That way you will be set for the GT35R kit I will talk you into buying in about 6 months or so
