During passing at 90 to 95mph. Slowly rolling on the throttle I am getting a fluctuation between 2500 and 3000 rpm up and down several times until I get off the throttle. Tuned with ezlynk w/ transmission tune. No codes and the rest of the time everything seems fine. How screwed am I?

When is the last time fluid was changed? Also was this a issue before the tune was installed? Also was it scanned with a good scanner that can read tranny codes or just a reg run of the mill cheap scanner.

Can you go faster than 95? The tune may have a speed limiter component that is poorly trying to de-fuel and hold you from giving more hammer.
