Finally had enough with the lack of throttle response on our new 6.7 Dodge. The best option for a more power and better driveability (corrected torque management) is probably EFI Live. The downside, of course, is that any tuning on the new platform 6.7 requires that the ECM be unlocked (sometimes corrupted and unlocked/reflashed). Done with the right tuner or sent out, this solution works great for those that can get away with deleting their trucks. But this is California, and the penalties for messing with stuff are getting steeper and steeper, so it may not be worth it. Not to mention that if you have a problem under warranty and your software version isn’t correct (and it isn’t unlocked) you are probably screwed–and these trucks ain’t cheap, so it wasn’t worth it for me
Enter BD Diesel and TS Performance. The TS Stryker promises 120HP/200TQ from a duration-only box that is DPF friendly. It is also invisible to the PCM and will not cause warranty issues (assuming it isn’t on there when you take it in) I installed one to test out and it did indeed add nice, linear power across the board. I’ll get it on the dyno later to verify actual RWHP numbers. It did not, however, fix the crappy throttle response in 1st gear.
The folks at BD Diesel sent down a Throttle Sensitivity Box. This thing takes about 6 minutes to install and calibrate and is OK for smog since it doesn’t actually change anything but the throttle signal. It has a “stock” “50%” and “100%” setting. I chose 50% to start and I was shocked at how much nicer it has made the truck to drive. Now the power happens “right now” and with the Stryker installed the combo is pretty sweet. This module is available for most modern trucks and some cars as well. For the money, its a worthwhile investment!
