Works great
Plugs in easily and keeps it in v8 mode. Works like it should and I’ve had truck sit three days without use and start right up so doesn’t drain battery to bad

Tahoes transmission shifting.
It did exactly what it was supposed to do, now I enjoy driving my Tahoe without that changing from 8 cylinders to 4 cylinders driving me crazy, I highly recommend it.

Says it wont hurt your vehicle, thats a lie.
Not good for your vehicle, keeps your check engine light off and wont let your vehicle tell you if there is a problem that needs attention. Do not use. If something happens and your check engine light needs to come on,this device wont allow it. It clears your dtcs without your knowledge. Wouldnt recommend

Works just like it's supposed to -- no more v4 or v6 mode, eliminated the hesitation !!
