How high can I set my shift points and rev limit without pushing it

6 speed. And how do I remove rev limiter not speed limiter but rev

Okay thanks the tune went on worked perfectly I'm curious I believe the truck shifts at 5500-5800 rpms how can I change that and how high can you go without doing any damage? Thanks

I have a trinity that came off a 2007 Tahoe it is not married anymore, what do I have to do to tune my 2017 Silverado 5.3 I heard it's different then tuning before due to change in computer is this true? Anything special I have to do? Please information on tuning a 2017 Silverado?
