I have a dodge 2004. 5 Ram truck and I have been thinking about installing 3 new gauges on it. These gauges are turbo boost, EGT, and an automatic transmission temp. gauge. I was talking to a Dodge Tech. yesterday and he said I didn't need any of these gauges on my model truck, that it had all of these gauge capabilities already built in to it. I am thoroughly comfused now. I have been reading in the TDR where these three gauges are very important in monitoring the performance of the HPCR cumming engine. Can someone please help me out on this. I don't want to buy these gauges and install them If they aren't really necessary. Please help thank you.
