I own a 93 R/T Turbo that will not rev past 4000rpm at full throttle. When driving it nicely it can rev all the way to redline but after going about 2/3 throttle is sputters and actually slows down. Logging the car shows no knock and I did notice the injector duty cylce actually went from high 60% down to 40%. It also makes a very loud popping sound that sounds like its coming from way over on the passenger side. Any help or ideas would be appreciated. I should also mention that the ECU is freshly rebuilt and switching ECUs makes no change. Thanks
Jake
