Message: [QUOTE="mharring, post: 1129333, member: 18236"] I have basic questions about the performance add ons i bought for my 6.4 Basicly ive never driven the truck. Bought it with some sort of engine failure. I have a low mile engine on the way to replace the bad one. I basicly bought a fx4 crew cab 6.4 from a crack head for 7000$ making a very long story short So to make this truck a solid daily driver and reliable ive bought the following Arp headstuds and cometic head gaskets Egr delete kit full removal Dpf/cat delete AFE atlas 4 inch down pipe back exhaust AFE stage 2 cold air intake Gearboxz dpfr tunner I guess my questions are about the total gains ill get from all the hard parts ( not the tunning) hp, torque , mileage?? And that dpfr has 5 tunes not to concerned with going mach 4. But what can i expect from these levels? How will they effect mileage? How will this effect hp and torque? Im very new to diesel performance anf am really only looking for mileage [/QUOTE]
