  1. Well, I learned several things on our trip from CT to TN. First of all, I need to speak with my tuner and find out if under driving the supercharger will keep me out of boost at certain rpm ranges. The tune in my truck is set up for the most horsepower, this does not make for the best towing, thank goodness it will be at least another year before I tow again. The second thing that I learned with a supercharger is, you cannot use cruise control! I love my cruise control, however, cruise control is set off vacuum, and when the engine starts making boost, the speed continues to climb and I would have to turn off the cruise. One thing that was very enlightening, was while entering the interstate and picking up speed, many of the semi's that were already doing the speed limit, were amazed that I was able to out run them by the end of my on-ramp. I received many thumbs up from them. And lastly..…….when your truck is set up for getting the most horsepower, I found out that the average fuel mileage for 850 miles turned out to be approx. 6-7 mpg towing a 14,000lb 5th wheel
  2. Larry, The issues that I had were from incorrect instructions. What type of low-end issues are you having?
  3. The weather here in New England is hit and miss (snow and ice) but I will be towing for the first time since installing the Whipple. We are taking our 5th Wheel to Tennessee. I am excited to see how the increase in hp/tq performance pulls the hills through PA and then once we get down in VA and TN. I will post the trip once I have something to post. Oh, I also installed a Flex a Lite dual fan set-up pulling 6000cfm and leveled the truck with the Suspension Maxx leveling kit, very nice product. I came with stock spacers (I already have Bilsteins), and the kit come with from differential spacers which maintains the CV joint angle so the boots do not prematurally wear and also saves the joint.
  4. You can get ahold of him, tell him I recommended you to him. His name is Ted Jannetty https://jannettyracing.com Randy
  5. Hopefully someone will make long tube headers by the time you are ready for them. Nothing available as of now.
  6. I prefer the Flowmaster, check out their Super 50 muffler. https://www.flowmastermufflers.com/flowmaster/street-mufflers/
  7. Unfortunately I do not, it is included and installed with the intake manifold.
  8. Eric, Congratulations on the new truck. I am so very lucky to have a performance tuner over here that dialed my engine in after the Whipple install. You will read (if you haven't already) about people bad mouthing the E78 ECM. It is all about knowing HOW to tune it. My tuner actually calibrates a lot of Whipple's programs for them, so when speaking with them at the time of purchase, mention my guys name. I will PM you his info when you are ready. Knowing how systems on your truck work is very important. I do a lot of research before making choices and then confirming them with experts.
  9. Now the question is, do anyone know of a metal connector to take the place of that crappy plastic one. On my left valve cover, the fitting is in the back, and I am installing a catch can but do not want to use the plastic connector. Sorry, forgot to say that this is for a 2017 Chevy Silverado 2500hd 6.0l with SC
  10. Does it make a difference with a performance engine to get rid of this oem muffler?
  11. '17 2500hd 6.0L Long Tube Headers?

    Hey SierraHD17, you actually have long tube headers that fit a 2017 Silverado 2500hd 6.0l? I looked at Speed Engineering and was not able to see anything close.
  12. '17 2500hd 6.0L Long Tube Headers?

    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.
  13. '17 2500hd 6.0L Long Tube Headers?

    I can't believe these headers are so hard to find. I was hoping one of you experts would have answered me right away...….
  14. 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.
  15. 2015 6.0 Drivetrain Clunking?

    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.
