I saw a YouTube video of an lb7 and the owner cranked the truck and then I saw him flip a switch in the cab and the truck started loping. How is this acheived? I was under impression it was a tune from efi.

It's is a DSP 2 or 5 switch. He is using EFI. I have a lope on my race tune to know that I'm at the end of the switch and it sounds coo. And I'm sure it sparkZ03dmax

I searched for lb7. It was one with a red cc. The switch seemed to be installed by him. It just looked like a small toggle.

Lope Switch

i have a 03 chevy single cab 4x4 6spd manual duramax with a lope switch i installed myself with no tunes, anyone with a dmax can do it. locate your fuel pressure sensor (on an lb7 its right under the intercooler boot on the driver side) and you will find it has 3 wires (power, signal,and ground) cut the power wire and wire in a toggle switch (flip the switch to the on position before cranking the truck) when the truck is running flip the switch off and the truck will begin to lope. it does throw a code but all you have to do is clear it with your programmer or scanner. It makes the same lope efi live tunes make. email me if you have any [email protected] [email protected]
