Trifecta Tune Requires Premium?
 
So my friend told me that if i tune my l61 with trifecta that my car is going to require premium fuel and im gonna be getting 25mpg instead of 35, wtf is that true?

Depending on what you have them tune, Yes you may need to run a higher octane fuel. A friend of mine runs plus in his now but still gets 30+ MPG.

well theyre gonna tune my l61 with bolt ons such as CAI, catback, grounded TB, tranny mounts, shiftplus, LSJ header, and soon with the 2.4 manifold and downpipe,,,,will i need premium then

it depends on the tune, not your mods. if you want more out of your tune then put in premium. Ive found i actually get better gas mileage since ive been on premo gas...but maybe im just driving it nicer

tell them to tune it for mpgs and regular octane instead of HP. Thats my plan. maintain current HP, but boost more on the MPG side. as odd as it it, but I drive like a granny so I have no need for speed. just fun projects.

lol. i figured, but just showing you you have options. its a custom tune which is why it's pricey.

The trifecta tune will actually improve your MPG. But if you have lead foot, your MPG will decrease. I'm fully bolted and Trifecta tuned as well.
