98cummins specs

From : cam olfert

Q: can anyone tell me the peak power and economy rpm points for a 98 12 valve cummins i have a feeling the best mileage happens around 1100 but would like to get some more input. fuel economy is usually best just above an engines torque peak. in the case of the 12v cummins thats around 1700-1800rpm with peak torque occurring at 1600rpm. .

need a second opinion i am having pricol optix gauges installed on my 2004 ram ctd in the next few weeks. i like the optix gauges because they match the oem dash. http//www.danininc.com/opticdetail22.html mounting will be a 3 pod dash mount. i want a tranny temp pyro and i thought a fuel pressure gauge. however the guy doing the install feels that i would be better served with a rail pressure gauge since the pump issue in my model ram is no longer an issue at all. would like opinions ... i thought about a boost gauge but cant really think of what that gauge gives me that i cant tell without it. tia. craig c. .
