EirCore™ AFM/DFM Disabler – Keep Your V8 Running at Full Power
❓ Will it fit my truck?
❓ Will it fit my truck?
Will it work on my truck?
EirCore™ fits 60+ GM V6/V8 models — trucks & SUVs from 2007–2018 (Silverado, Sierra, Tahoe, Yukon, Suburban, Escalade) plus select cars 2004–2019. Engines: 3.0L/3.6L/3.9L/4.3L V6 and 5.3L/6.0L/6.2L V8. Doesn't fit 2019+ models with DFM/10-speed transmissions or 2022+ refreshed trucks. Email us your year/model and we'll confirm fitment.
⚙️ Is this a tune or a delete?
⚙️ Is this a tune or a delete?
How is EirCore™ different from a tune?
EirCore™ is plug-and-play — no programming, no tuning, zero ECU changes. It sends a passive signal that prevents AFM/DFM activation. Unplug anytime and your truck returns to 100% factory settings instantly. A tune permanently modifies your ECU.
🛡️ What's your guarantee?
🛡️ What's your guarantee?
90-day money-back guarantee. Not satisfied for any reason? Return it within 90 days for a full refund. Every unit is also covered by a 12-month warranty on the module itself.
🔌 Will it throw a check-engine light?
🔌 Will it throw a check-engine light?
No check-engine light, no codes. EirCore™ doesn't write anything to the ECU, so it triggers no fault codes. For OBD inspections or dealer visits, simply unplug it — the port is free in seconds and your truck reads 100% stock.
📟 How do I know it's working?
📟 How do I know it's working?
Watch your dash. On 2014+ trucks, the Driver Information Center shows V4/V8 mode — with EirCore™ plugged in it stays in V8 and never drops to V4. On earlier models, any OBD app shows the same. The blue LEDs confirm the module is powered.
