Hey guys new to tuning,been doing a lot of reading. Can some one tell me the best way to add 5% fuel above 4000 rpm?s in my 1999 c5. It about 13.2/13.3 and want to be more around 12.8.

Is the wideband reporting 13.2-13.3 but the commanded AFR is still 12.8??
Without seeing how your tune is setup and seeing a log file, that is why I asked.
Fuel is added in the MAF and VE tables depending on which portion you are tuning and how it's all setup.
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.
ECM 12400
Fuel> power enrich> EQ ratio (gas)
You increase to add fuel,decrease to remove.
13.3should be like 1.1
12.8 should be like 1.15
Best way to add 5% is to command 5% more.
