Yes, you have to use a computer with LS1Edit, HPTuners, EFI Live, etc.

I would not raise the rev limiter on a stock motor.

1) There is very little (if any) to be gained by doing so.

2) The stock valvesprings aren't very good above 6200rpm (which is what the stock limiter is set for).

Not worth risking the damage. Your money would be much better spent buying some simple bolt-ons first rather than worring about tuning changes on a stock motor.

+1 Ive told so many people not to mess with this. You probably have seen some videos of F-bodys reving very high, they have the stuff under the hood to do this. Dont mess with it. Like RPM said, you wont see anything anyways.

No point in playing with fire on a stock LS1. You're money would be much better spent on a 3400-3800 stall torque converter and a transmission cooler

Good choice.

Leave the rev limiter at the stock setting until you get some aftermarket valvesprings.

Not to steal a thread, but for LS1 guys with around 100K miles, where does valve float occur? Are the springs solid enough to withstand stock rev-limiter ranges even in the higher mileage cars without float?

And when you do do it, dont hand held do it, get your mods on first and take it to a dyno and get it tuned on the dyno, let them tune it correctly for you and have them change everything, remember they are pros and doing this.
