Do you mean a "rev limiter"?

are you trying to make your 17 bounce of the rev limiter like a gen 3?

Ok i have asked HP tuners for the IMMEDIATE TORQUE TYPE and they said its no longer available. Since on OLDER trucks upto 2016 is set on PLEASABLE, i have done the following:
Go to SPARK >>> ADVANCE and in MINIMUM FINAL SPARK where your vehicle is on REV LIMIT start with 5 DEGREES and it should give you the rev limiter. Please note that this is not the right way cause in any case your TIMING will never go below 5. 10 DEGREES will make it faster.
You need to still set the other parameters like Switch OVER DELAY etc to make it WORK and I have tested on 2017 GMC and is working ok like 1500 5.3 Sierra/Silverado.
TEST ON YOUR OWN RISK !!!

In the Cutoff/ DFCO tab it will show your rev limiter in there. Keep in mind, if you are looking to get more revs out of it you will have to raise your WOT shift speeds in the trans section as well. I did this on my 17 Silverado.
