I just setup my new MM3 this evening which was pretty easy after watching all the DIY vids on youtube. My question is, can i still run my truck without taking any of the hardware off? (i.e. EGR, Throttle Valve, exhaust). I'm heading into town tomorrow morning and i just want to know if i can run it with everything intact. I have the complete option tunes and DON'T have the EGRless. I plan to do the rest of the removal tomorrow afternoon. Let me know thanks!
You cannot run it with stock exhaust intact. Everything else you will be fine.
Just out of curiosity, will it jack anything up? I started the truck after i flashed the ECM to make sure that it still runs and see if the CEL would come on. While parked, i cycled through some of the sound tunes and yea nothing changed, it still sounded the same....Go figure! I guess i'll rip the exhaust tonight in the frigid Carolina CrispQuote:

You could be where I’m at. They are calling for 2 feet of snow here. Ughhhh!!!
Yeah you will have to remove your exhaust or else your truck will go into limp mode. After that you will be able to hear the sound tunes then. [emoji106]

I just finished the rest of the deletes today. I started at 7am and finished at 1:45pm. I have to say that the hardest part was the dang exhaust, i heard that it weighed alot but that wasn't the problem. I sprayed water and soap on the rubber hanger gromets for the exhaust system to ease the removal process. I also found that dropping the spare tire helps alot so you have more room to remove the tail pipe. The second hard part was removing the EGR, the videos on Youtube make it look so easy but damn, thank god i had a breaker bar and a deep socket. Then there was the dreaded 15mm nut at the front of the EGR, I just went ahead and removed the entire EGR and the bracket, then made my way to the front. Everything else was easy and direct replacement. Ive seen that some people drain the entire coolant, but i didnt fing that necessary. All i did was cover the turbo and grab a small 20oz. bottle to catch the coolant, which worked out fine. All in all i would say that it was definitely a challenge but doable even for novice mechanics.
After i put everything back together i took it for a test drive and like you all have said "it really wakes the truck up". The throttle response was awesome, it didnt shift hard (shift flare) and the sound tunes are awesome. I didn't run the engine hard, just did normal driving for the "Relearn" process to take affect. As for the MPG increase, i have not seen a signifiant increase, but i'm hoping with time that it gets better.
I want to thank @dudesdieselperformance @watersupply189 for giving me advice, both directly and indirectly. Most of all i want to thank @IGOTACUMMINS and ray from @DRD for helping the community by posting videos and testimonials for us to be able and read and further educate ourselves.
Glad you woke the beast up! Yeah those exhaust hangers can be a pain sometimes.Quote:
