I have a 1994 Supra NA-T. I dropped it off at a well known performance shop in Las Vegas to get it dyno tuned. A day later I get a call from the owner who is working on my car, and he told me that the MAP-ECU will not work with my car, well he said it wouldn't be safe. He told me that since there wasn't any ignition control with the MAP-ECU that it would not be safe to run it on my car. He told me that when boost kicks in timming should be backed off. Aren't there a lot of NA-T guys running MAP-ECU with no problems. WHAT SHOULD I DO??????
