Frequently Asked Questions
What is a delete tuner?
A delete tuner is a device that reprograms yourtruck's ECM (computer) to turn off emissionssystems like the DPF, EGR, and DEF, allowing yourtruck to run without those components
Can l use a delete tuner withoutphysically removing TheDPF/DEF/EGR parts?
You MUST remove your DPF(Diesel ParticulateFilter), as the filter will clog and stop all exhaust flowwhen shut off. You will no longer need DEF(DieselExhaust Fluid), and you may remove your DEF tankif you wish, or it can sit empty. The EGR may remainas is, but we recommend removing the physicalparts as well.
Is a Delete Tune bad for mytruck's engine?
Quite the opposite. In fact, many customers reportimproved engine life, smoother shifting, and betterfuel economy (typically 3-5 MPG gains) when usinga quality delete tuner.
What's the difference between adelete tuner and a delete tune?
The tuner is the hardware device. The tune is thesoftware file that gets uploaded to your truck's ECM.Your delete tuner includes a delete tune when youpurchase from us.
Do delete tuners void my warranty?
Yes. Any emissions-related modification, includingtuning, can void the manufacturer's warranty. Manycustomers wait until after their warranty expiresbefore deleting.
Do l need a mechanic to install thetuner? How long does installationtake?
Not necessarily. Many of our customers install their delete tuner themselves in under 30 minutes. We include easy-to-follow instructions, and our support team is available if you need help.
Will my truck pass inspection oremissions testing with a deletetuner?
No. Delete tuners disable emissions systems, so your truck will not pass emissions tests in areas where they're required. Some states have exemptions (e.g. heavy-duty or rural-use trucks).
Can l go back to stock afterinstalling a delete tuner?
Yes. However, in most cases you will have to have the ECM flashed at the dealership. If this is a concern, contact our team and we can explain further.
