Why I switched from DRD to CTT
I ran Ray's tunes on my 2017 2500 CCLB and I loved it until I rode in my friend's truck with CTT tuning. He had considerably better fuel mileage and a much more responsive transmission. So I went with EZ Lynk and CTT tuning and here is my experience:
A little about me and my truck:
I have a Thuren leveling kit with 35's. I am studded with ARP 625's and I have a REVMAX valve body. I only run Max Effort all day every day, no matter what. It feels better, and I get way better mileage and that is what I like. My normal driving manner, depending on who you ask, would be described as "normal" to "a little hot"; sorry there is no objective way to describe this.
Mileage:
I was getting low 16's with DRD and now I am getting upper 17's with HPP when I drive in my normal manner. When I am conscientious of mileage and I want to see how good I can get, I get high 17's to low 18's with DRD and I get low 19's to low 20's with CTT. This is on my way to work, which is mostly two lane highway; and the comparison is under the same duration, traffic, terrain, atmospheric conditions, etc... The only difference may be how many red lights I hit across a tank of fuel.
Transmission:
With DRD there was a ton (excessive amount to my taste) of shift flare across all shifts, and you always jump through the gears too quickly and you are lugging unless you are in tow/haul, and if you downshifted under throttle the flare made it feel horrible and your power is lost in the abyss that is the unlocked torque converter. With CTT the shifts all feel quicker and firmer and you feel like you are actually getting somewhere. There is still a bit of flare in the 6th to 5th downshift which I don't like. I know that locked shifts are hard on shafts, and I know all about why shift flare is designed into the transmission shift strategy. Please don't respond to tell me about that. DRD has excellent videos explaining it if you have any questions. Ray's videos are extremely well made and when I was getting started he taught me a lot, because he knows what he is talking about, and that is why I chose to purchase his products. Go to Youtube and watch his videos and you will learn from him as I did. Sorry I got off on a tangent there.
EZ Lynk:
Now that I have been using this for a few weeks, I can tell you that EZ Lynk is far and away a better platform than MM3. Hands Down. Updates are sent to your cloud and you just select it and upload it to your truck from your app on your phone. Done. MM3's display quality sucks. SUCKS! SUCKS! MM3 display is small. I can put the EZ Lynk app on my ipad, phone, whatever, so the gauge display is as big as I want it. I can tune my truck from my ipad! That's cool. When I want to contact my tuner to BS or ask a question, or say "hey, what do you think about this?", or "hey, could I do that?", you do it right thorough the app!
CTT:
If you are worried about your money and are ever considering changing a hard part, but are hesitant because you dont want to pay for a retune your days of worry are over. With CTT it is a FREE RETUNE. If you ever change a preference, FREE RETUNE. I am going to a Firepunk 48RE with an Anteater and a Porcupine. I have talked to CTT, they said no problem, we know all about that and we have excellent success with that, and guess what?? FREE RETUNE. When I do a 72mm 2nd gen swap, larger injectors and dual CP3's... FREE RETUNE. I can data log through the app and send it immediately from the app and they will fine tune the revisions for me, and the response time has been extremely fast so far.
To see the response I got from DRD and the moderator on IGOTACUMMINS when I recommended CTT, Look up the thread and you will be shocked: "Attacks On DRD From Within This Forum"
