99-00 Miata PNP Kit

These guys are great especially Issac. He always helps me and hooks it up. The ecu does what it’s supposed to do if I could just learn to tune better. My only suggestion is speedyefi you tube channel for setting up the ecu and basic tuning functions. Then videos for setting up the extra parts you can get from them. Or instructions with pictures on the website for the same things…or both! That way I don’t have to ask so many questions. Ecu is pretty easy to setup though I must say. Way easier than hptuners for my corvette! Thank you fellas for quality products and customer service experience! I really do appreciate it. You go above and beyond on customer service! I highly recommend buying a speedyefi if debating it versus the competition. 5 stars from me!!!
