How much of a difference in temperature would you see in programmer vs gauges? I use a program called Torque pro and I can monitor my EGT was wondering how off that is. Reason I’m asking is I do tow and I have the PPE but I’ve been told by PPE not to use level 3 and 4 without gauges as I can really hurt my truck.





Or is there anyone in Phoenix that has gauges that we could meet up for 5 minutes to see the difference?
