hey hello there i have the Jet DST software and had to try on two GMC sierra 2011 and 2008 5.3 v8

i want them to bounce off the rev limiter quickly for what i did is went to

constant>system parameter>extreme fuel cutoff RPM 6100 extreme fuel resume RPM 6098
table>system table> fuel cutoff vs RPM changed both Park and Neutral to 6100

no when i test it i goes all the way to 6100 and stay there without bouncing off


help please
