Default LS6 vs. LS3 *DYNO GRAPH*

All pulls were with crappy CA 91 octane.

My 04 z06. BONE STOCK. Best pull: 359.90 HP 346.82 TQ SAE

My current 08 C6 (MN6). ONLY modification is Borla Stingers. Best pull: 382.42 HP 371.55 TQ SAE

The LS3 has noticeably more power through both curves from start to finish, very stout motor!!

Sorry for the poor quality

Do you have a tune on the LS3 with those Stingers?

I understood what you were asking initially. There car still has the factory tune for now. Yes, you can get a tune no matter what.

Good to see the LS3 has that kind of power, and a very nice comparison to its sibling.

The fact that the LS3 makes MORE power than the LS6 is impressive and not surprising, what I find interesting is how these motor's propel the respective car's they are installed in.

What is interesting is the LS6 seems to have a touch more hp per liter of displacement. That appears to be a strong LS6 and an average LS3 from all the numbers I've seen.

I love my LS3.

Thanks.

I love the way the Stingers sound on startup, idle, acceleration, cruise....simply awesome! Very little drone, too. I do NOT like the way they burble/pop on deceleration, but all of the "louder" exhausts I've had did the same, so I'll live with it.

I agree. My LS3 bone stock (with NPP) did 390.5 on the MTI dyno. His could read low, but the LS6 is a little higher than what I typically see. Good info!

It doesn't read low, I think my car makes good power, especially for 91 octane. I'd say your car made above average power.
