I unfortunately allowed e85 to be ran on my engine and my tuner noticed that my fuel trims were wonky and suggested that I service all injectors. Rather than spending $250 on getting them serviced, decided to invest in a cleaner/tester so I could do injectors for my other cars. When the CT500 was delivered, some of the fittings in the slide out box had shifted around from shipping, but other than that it comes with many different sizes/fittings for whatever your application is. Pretty intuitive to use, and all of the testing functions are pretty helpful. In my case, you could see a difference in the high speed tests showing that 2 of the injectors were spraying unevenly. Threw them in the ultrasonic tank for the recommended time, retested, and BOOM they were perfect. I used 99% rubbing alcohol as the test solution. Would definitely recommend for a car enthusiast or even for an automotive repair shop!
