: Is the D-MAX safe without an exhaust clydesdale 03-23-2004, 07:42 AM I have a friend who is running a chip and some sort of box or something. The chip is adjusted with x amount taps on the go pedal. I am not sure exactly what products he has. But he is not going for larger exhaust. I know this is a no no with a 7.3 powerstroke because egts may climb to unsafe levels, but is it ok on the d max. Thanks sdaver 03-23-2004, 08:23 AM the unit is the juice and yes its safe with non towing situations but has restrictions while towing......guages are recommended when towing in power levels above level 2 standard juice VFRRider 03-23-2004, 05:50 PM If he doesn't want to spend, tell him to have the muffler yanked and straightpipe it. $45 Mark Craig 03-25-2004, 01:06 PM clydesdale, Don't want to upset anyone, but if they are towing any significant amount of weight they need to upgrade to the Attitude and or get a set of gauges. With enough weight and a stock truck on a serious incline you can get into 1300 degrees pre turbo fairly easily. Have him give us a call if he needs any specific info. Exhaust will of course lower those egt's, but gauges will let him know where he is at anyone moment. Mark @ DPPI 2MuchFun 03-25-2004, 02:31 PM I agree with Mark! You would be surprised how easily you can get the EGTs up high, even With exhaust. IMO some type of pyrometer is a must with any chip. 1bad01 03-25-2004, 05:10 PM I'v been told for drag racing porposes its ok to let them reach like 1500 or so just as long as its only for a brief period of time. So.... What is the highest sustained egt you should allow your truck to reach while towing or climbing a big hill? sdaver 03-25-2004, 06:42 PM 1300 preturbo | ||
