I have been spending a fair amount of money with ZZP lately and hopefully will have the 3.4 setup with supporting mods in by fall of this year. Has anyone had them dyno tune their vehicle? I did not hear about this service that they have, but it says so on their website. I know that I should stay away from their mail order tuned PCM's but wondered if anyone has any experience with them on the custom dyno tune end of the service........Thanks
