I was just wondering what would be the cost to have a dealer install the High Idle on a 03 Duramax. Mine has the Cruse and Allison Transmission. I was quoted $300.00 by a dealer in another town. I thought that was a little high.

The most they should charge is 1 hour labour and maybe $10 parts tops.



I can do them in under 1/2 hour and I go to a lot of trouble with loom etc to make it invisible.

Max Power, I wish I lived closer to you, I would have you install it for me. I have been down in the back since Christmas time, not able to do much for myself.

I live in Calgary Alberta Canada and had my fast idle put in by the dealer for $110.00 Cdn. That would be equal to approx. $75.00 US
