SierraHD17, I understand that you do not like this ECM and have issues with tuning, but as I have posted in my Whipple SC post, my truck is running so good after my tuner did his magic, that I would like to go with long tubes to add to my low end. I pull a 14K 5th wheel and the more torque I can make the better. You mentioned that you have speed engineering long tubes for your '17, but would they actually fit without modification? Trust me, I never knock anyone's opinion, but my truck just runs awesome.
Ok, I have looked for quite some time and have failed to come up with any company that makes long tube headers for my 2017 2500hd 6.0l. Can any one of you lead me in the direction of this product? I was really hoping that Kook made them, but only for the 1500.
I learned today that the noise that we are hearing in the drive train is coming from the transfer case. The sound resonates from the transfer case down the drive shaft, so it sounds like it is coming from the rear differential. It is normal.
Ha e you looked at the Roadmaster suspension? I had one on my 1500 and it worked great. I ordered the u clamps to fit the 2500 ut never installed due to the heavy weight of my 5th wheel trailer. They ride very well and installed in maybe an hour. I still have them if someone wants to buy them. Sent from my SM-N960U using Tapatalk
I am including some photos of the Whipple Supercharger Kit Entire kit before install Supercharger views from side and from rear including the blow off valve See next message for additional pics
I took the truck for a performance run to see what my boost gauge and fuel pressure gauge were reading. From a rolling start going about 25 mph accelerating to 110 mph, my boost was just a tick under 10 psi and fuel pressure was approx. 65 psi.
I get around 10-13 mpg around town, and on a trip to upstate NY without a proper tune and driving 65 mph on the interstate with the cruise control on, my "best" was 18.3 mpg. I am not seeing that now a days because I can't keep my foot under control, this truck is so much fun to drive now.
The entire price was around 900.00. That included 3 hours of fine dyno tuning, transmission remapping, changing the shift points for towing, and welding in 2 bungs on the exhaust for his dyno. I spent so much time with a few issues in the beginning because of trying to tune by email. My guy mine done in one day and it runs awesome. I know one thing for sure, going up route 8 through CT, the highway as you probably know is hilly, going up 3 and 4 % grades, the trans never shifted out of 6th. Pulls the gears so much better.
I purchased the kit directly from Whipple, it includes the HP Tuner kit and credits. The towing will have to wait until I take my 5th wheel out of storage. If you ever decide to install this kit, come to CT and use my Tuner.
