You're doing it wrong
Stealth module usually bypasses the computers ability to dial back the fuel because of the way the module works thats the issueI was monitoring EGT on class 8 trucks since 78 . In modern electronic engines they did away with the gauge as the computer will prevent the EGs from destroying the engine . With a tuner I imagine you may want too . The truck is fast and powerful enough for me as is .It wasn't too many years ago you would've had to spend serious money to get the power that is in a stock engine of today .
