What is your reason for not using Autowave? Jon is very good and would be a good alternate choice, but Autowave has lots of experience in the CTSC for the NSX. Besides the installation and other mechanicals, tuning is a HUGE part of what you should be looking at. They have an in-house dyno. Mike Lapier is an excellent tuner with extremely valuable experience with the AEM ECU (he will find the right tune and maximize your HP for your setup). Mark Middleton knows the NSX, mechanicals and diagnosing, better than anyone I've ever worked with. Shane runs a successful business by being professional, reasonable and above all, careful. Their business philosophy of car repair first, then car tuner second has worked well and they have a thriving business. Eventhough I live in Las Vegas, I chose Autowave to work on my project car (In 13 years of NSX ownership and roughly 11 years of modding it, I have seen many many shops and tuners come and go- no longevity if you are one blown engine from starting the cycle of robbing Peter to pay Paul). Good service at a reasonable price and the knowledge and experience to back up their work is the reason why you should reconsider Autowave.
