Most people do, but that is the lay of the land. We recently had a 996TT with one of those reflashed DME's in because it would not pass the state "advanced" emissions test for inspection. State said they could not read one set of the O2 sensors, yet on the Durametric system, the car looks fine. We reflashed the car back to stock, and the car passed without problem. Some these aftermarket flashes do some weird things to keep the car code free, but the state system catches it.
Over the years, we have had a chance to see cars run on the dyno, then re flashed and run on the dyno again. The real world differences were not all that great. When we questioned the companies sell the flash, the response was always the same: The car still needed this, that and the other thing before the flash would deliver big numbers. Even with everything they said the car needed, the numbers were still not all the big.
The owner of 996TT that failed inspection decided to leave the OEM program in place, and after multiple track sessions, the car's track numbers were no different, the owner said he did not feel any difference in the car.
