If it's a stock 5.3, I wouldn't just free rev it that high. Not without better valve springs, plus you are way outside of the usable range for the camshaft at 6,300rpm.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Well its not stock it has some bolts on i just want to know how to rev it like a bike
