Mountune for Raptor

[Pacific Wheel]

are their scenarios where a e tune wont be a able to replicate vs a dyno tune and vise versa?

From my experiences with both, the e-tune is more time consuming. On the dyno they wrap the tune up in one session usually. For my e-tune, the tuner sent me a base MAP and I had to go log data. For the STI I had it was a few pulls in 4th gear from 2500/3000 rpm to redline. Email each log and the tuner would make tweaks until it was perfect. My e-tune was ran very well.

what are the disadvantages of a etune vs a dyno tune?

Disadvantages of an etune (such as the current Cobb offering) is they are general vehicle specific, not "your" vehicle specific. While a Dyno tune is specific to your vehicle and may provide the best gains, finding a reliable tuner can be a challenge. A tune like Mountune is kind of in the middle, it starts out as a cannned tune, but then you do a bunch of data logging and send the results to the tuner via email who then modifies each previous version accordingly until you are in the sweet zone.

Etune is vehicle specific.

Cobb is not offering an etune. Just a canned tune.

Mountune does etune for your car. More time consuming then dyno but results are very similar.
