I have a 2009 Chevy Silverado and I tuned the truck but I don't really understand how to set up the rev limiter ?
Right now I red line at 4000 Rpms I want to red line higher so how can I adjust it ?? Can you guys help me ?

the 4K rpm limiter is in Park/Neutral, and is there to keep you from hurting the engine or trans, you can use the neutral rev limit adjustment in the modify parameter menu to raise it if you desire, but the limit in gear is up around 6K RPM.

Thanks

So I can't rev higher than 4K rpm in park ?
I want to rev higher than that ...

And how do I change that on the tuner it goes by 50 , 100 etc what does those numbers mean ? How do I know how much I'm going up by ?

you can not adjust rev limiter in park/neutral.. only for in gear..

you would need a custom tune to be able to have the rev limiter set higher in park/neutral..

but it's not good to over-rev/free-rev the engine in park/neutral with no load on the engine anyway...
