Lund Emissions Tune

[bluebeastsrt]

Just asking. Why install a Flex and E85 tune and keep switching back and forth? What do you hope to gain?

You gain power on e85. Say on days you want to hit a track or drag strip. And you can still run 93 the rest of the time. The beauty of the flex tune is the convenience. You can have a half tank of e85. Put 93 in and the car. And the car is still happy. I have a dedicated e85 tune for my supercharged car. It’s best if I empty the tank. Before I fill up with e85. As the car will throw codes if I start mixing fuels.

I can see a boosted car getting enough gains to hassle with swapping.

Just thought about switching back to factory tune to pass emissions soon.
Can I leave in LU47’s on factory tune or do I have to switch back to stock injectors?

Sorry for reviving a dead thread but I just loaded my emissions tune from Lund and had all the monitors set in about 20 mins of driving. Mods jlt intake,18 manifold lu47s corsa cat back, stock cats.

Same here lol, sorry for reviving this dying thread. I have the exact same mods and I received the Lund tune emissions file and loaded it and the car just wants to continually die unless I give it gas. Not to mention the IM monitors never fully come on regardless of how much driving I do, I also get many DTC errors...so odd

I'd love to see someone who got everything to go green that has long tube headers. That's the struggle currently.
