During the next few days I will be havin a Motec M800 OEM put in the car and a few maps built for my needs, now granted it will need to be re-tuned in the spring/summer months so I can get the best possible power out of the car. I was going to go with the AEM but decided against it, plus my motec tuner is a good friend of mine and couldn't pass up the deal. Figure the average schmo will pay upwards to 4k for a base m800 system but mine will have everything I want for a mere 2.5k fully mapped.
off topic- below is a shot from Deals Gap in NC, fun road for you street deamons out there, 11 miles of constant switch-backs in all different elevation ranges.
