If I get the Trifecta tune with K&N SRI do I have to always have the tune on? The reason I am asking is because with stock tune with intake skews the fuel trims right? I would like to have it off if Im not racing someone or going down the track.

I have the KN short ram with trifecta switchable tune with the cruise control. It works fine, you wont need to put it into stock once you see how it feels with the tune.

Once you get a Trifecta tune, there is no more stock tune. You get to choose between two pressures, but they're both Trifecta tunes.

No you still have a stock tune just in another file

Trifecta isues two seperate tunes in one. a high boost and a low boost application, the high boost setting will be your performance tune. and the low boost will be for daily use or whathaveyou. both the tunes will be optimized for any mods the car has

You also forget the factory settings. In the past it came as a 2nd file. Now the new ones you pick custom or factory

yes you can now select the custom tune or stock tune on the same file, this is BEFORE loading the tune to the car though....while the tune is on the car you will only be able to select from low/high boost settings

I get what your saying but someone about said you don't have a factory tune anymore and I wanted to clear that up.

yes in that sense you will always have you rstock tune file on back-up just in case!

See us dealers know.

You don't have the factory file on your car's ECM. How about that?

That's what we're saying but above someone made it out to be like you can't go back
