We have customers frequently asking about custom tunes for their deleted Cummins 6.7 trucks. However, most of them do not need a custom tune for their current setup, our standardised tunes on the RaceMe Ultra supports even moderate race applications.
Is a RaceME tuner and BBI Injector the best combination for getting full performance of your Dodge Cummins 6.7?
So there is no need for a custom tune if you only upgrade your VGT turbo with a larger non VGT turbo. Removing the grid heater is also supported and will not give you any DTC codes. Putting in slightly larger aftermarket injectors do not always require a special tune also. With larger injectors, you will get larger quantities, especially at full load conditions. But that is what you want. Aftermarket injectors will not flow more under light load conditions as we are now talking about injectors we want to state here that we only recommend using BBI injectors. As the BBI team was involved in the development at Bosch, they are producing superior injectors compared to any other aftermarket injector we had our hands on. So if you think your 6.7 Cummins deserves the best, a RaceMe Tuner and BBI are what you should look at.
If you add really big turbos and lose a lot of boost in the low rpm range, and you want a clean running truck also in that area, custom tuning can make sense as the standardised tunes will then provide too much fuel in low boost range.
On the other end of the rpm range software tuning can get to its limit. You cannot increase the duration and timing endless. Especially with higher rpm’s the timeframe for an injection gets shorter and shorter so only a hardware change can get you more fuel into your combustion chamber.
With Warp tuning the sound of your 12V will make much better noise!
On the 12V sound and lope tunes we suggest to use Warp tuning and create that tunes as an „RTP“ program which can be added to our standard programs selecting it and adding it as an RT (real-time) feature. Therefore you need a Warp dongle and some knowledge or at least a friend with knowledge. However, it is not very difficult to remove the pilot injection to generate the 12V sound.
Another advantage is that you even can create files for your friends 6.7L Cummins truck without any additional costs.
