Q1: What’s included in the SPELAB LML full delete kit?
A1: Our LML full delete kit includes everything needed to fully delete your 2011–2016 LML Duramax: a Mini Maxx V2 Tuner, LML EGR delete kit, LML DPF delete pipe, and 5'' downpipe-back dual exhaust system. It’s an all-in-one solution for improved performance and engine longevity.
Q2: Is this LML delete kit compatible with both Chevy Silverado and GMC Sierra?
A2: Yes, this LML delete kit fits all 2011–2016 Chevy Silverado and GMC Sierra 2500HD/3500HD trucks with the 6.6L LML Duramax diesel engine.
Q3: How can I tell if I have a 2015 or 2015.5 LML Duramax?
A3: 2015 is a split model year.
-
2011–2015 trucks use a V-band clamp on the downpipe.
-
2015.5–2016 use a 3-bolt flange connection.
Visually inspect your truck’s turbo downpipe clamp before ordering a 2015 LML delete kit to ensure correct fitment.

A4: Yes, the Mini Maxx V2 Tuner comes preloaded with delete tunes that support DPF, EGR, and DEF removal. It offers multiple power levels and built-in diagnostics, making it ideal for use with a LML full delete kit.
Q5: Is this LML delete kit legal in Canada?
A5: No, this kit is for off-road and race use only. It's not street-legal in emissions-regulated areas like Canada or California. Please confirm your local regulations before ordering a LML delete kit Canada.
Q6: Will installing this kit trigger a check engine light (CEL)?
A6: No, as long as you flash the delete tune with the Mini Maxx V2 before removing any emissions equipment. This disables related sensors and prevents CELs during or after installation of your LML DPF delete kit.
Q7: Can I daily drive my LML Duramax after the full delete?
A7: Yes! Many users daily their trucks with a LML delete kit installed. You’ll notice better throttle response, increased MPG, and reduced regen-related issues. Just ensure all deletes are done correctly and understand it's for off-road use only.
Q8: What kind of power gains can I expect from this kit?
A8: With proper installation and tuning, a LML full delete kit can add 50–80+ horsepower, improve torque delivery, and lower exhaust gas temperatures—especially when paired with the included upgraded exhaust system.

A9: No custom tuning is needed. The Mini Maxx V2 Tuner is preloaded with proven delete tunes. It works right out of the box with SPELAB’s LML EGR delete kit and DPF delete pipe—no extra files or shops required.
Q10: How long does it take to install the full LML delete kit?
A10: Installation time depends on experience:
-
DPF pipe + tuner: 1.5–2 hours
-
Full EGR/DPF/DEF delete: 4–6 hours

We recommend setting aside a full day and using a lift if possible for easier exhaust work.
