This may seem like a stupid question to some but i'm still learning about the LS3 5th gens in comparison to my LS1 4th gen.

The car is a 2013 1LE, so please keep in mind the gearing is a little different. When my warranty is over I plan to get exhaust and tune, when I do go for the tune I would like to raise the rpm's a bit over what the factory rev-limiter is set to. What is a safe, but more than factory, rpm to retune to?

I have NOT really opened this car up much but I believe it currently sits at 6200rpms and it feels like the car has not reached its full potential before I have to shift, feels like it is still pulling strong when the rev limiter kicks in...again i believe it's 6200rpms or close to it when im topped out and have to shift.

Sorry if this is a stupid question, just trying to get some knowledge on what others have tuned theres too and been just fine.

While I have never looked at a specific 13 1LE calibration, every other LS3 calibration I've looked at has a 6600 rev limiter if it is a true LS3 and not a L99 or other 6.2L variant.

See 6600 seems more on point to what the engine is capable of than where Im feeling it limited. The 1LE does come with a different 6 speed manual than what the SS does and also 3.90 rear gears if that helps.

You should verify where the engine is making power and where the RPM drop would be in the next gear with a 6200 shift. I wouldn't go revving any higher without making sure that you are still indeed making power (butt dynos can vary).

Although I wouldn't be afraid to rev that to 65-6600 if necessary.

Absolutely get the RPM bumped up if it is not dropping off power. You want the shifting to act like a seesaw. You want to go over the peak just enough to come down at a similar place on the low of the next gear. Always stay near peak is the name of the game

I would bet your tach is lagging behind the actual engine rpm too.

Didnt think about that, you could very well be right.

I do feel though that the car still has alot of hear left in it before rev limiter hits, still making power and not noseing down
