I'm looking for a reputable shop in Rancho Cucamonga/Ontario/Fontana to install my Isspro gauges (pyro, trans temp, & boost on "A" pillar) that just arrived. Does anyone know anyone in the area that does/has done this type of work before?

I know there are a few shops in Orange County and one in Lake Elsinore but its nie-on impossible for me to make it down there during the week. I need a place where I can drop the truck off on my way into work and pick it up on my way home. Thanks!

 

Not sure of any performance shops in the area. However, I'm almost positive that there's a Cummins maintenance shop in Ontario. My local service writer said he used to do a lot of business with them when he worked up that way. He said they are pretty reputable and my service writer is a pretty straight shooter. You might wanna look 'em up and give 'em a try. They might be able to do the work or point you in the right direction.
