Oki......:) Now that you've decided to stick with the 98 octane fuel you can manually initiate the boost preasure adaption procedure simply by doing a series (3-4) of full power accelerations on a high gear (4th or 5th). Dependning on which ECU you have (T5,or LH242/DI/apc) your car will "learn" and adapt to its new environment (high octane fuel) between 2750-3250rmp or 2750-4500rmp........This is of course done automatically also, but that will take a bit longer.... /Mathias Johan A wrote: > After refueling today with 98, I went for a hard test-drive, and its just as > you said, the boost gauge goes a bit deeper into the red zone for a longer > time, and the turbo starts boosting on a bit lower revs.. > I think I'll stay on with 98... > > /Johan > "Mathias" <_nopsamm> skrev i meddelandet news:392296A1.BFF3C1B3nopsamm... > > If you dont notice any difference, run it on 95. > > > > In my experience there is a significant difference.
