When getting a reflash (EcuTek) or piggyback (UTEC or XEDE) which is better, a dyno tune or a road tune? Some EcuTek tuners only road tune. Which yields a better result?

IMO, a road tune is a lot more accurate to the real world the car will see. Thus producing a more consistent result.

So the "real world" is hitting speeds well into the triple digits while out on a tune? :D Hehe

I believe a combination of the two would yield the best results.

Hey... remember ;)

I just give the recommendation... it's up to the driver to decide if it's appropriate to do ;) heh.

With a subaru,at least with the ecutek, - road tuning is very vital as the active ignition timing control needs extensive driving time and real world conditions to reach an "adjusted level" only by logging and observing these actions by the stock ecu can the tuner note any changes which may be needed.

Dialing in the a/f is just like any other car and can be done ojn the dyno or the road.

Its the ignition adjustment feature which makes the subaru uniquely suited to road tuning.

At the present time, I am offering a special with all Dyno Flash ecutek tuning - you get 2 hours of custom road tuning AND a hour of dyno time with tyour before and after dyno sheets all included for FREE with the base ecutek flash. I feel this is what produces the best reusults.

It seems like some dynos produce more load than my car will ever see in the real world (I don't tow semis or boats), making the tune more conservative than it needs to be. Maybe that's good. I'd find the longest, steepest hill you can, and tune there, or at least if you develop a dyno tune that's agressive, test it on that hill regularly throughout the year.
