Recently had this company build me a wiring harness and program my computer. Excellent work. Thank you so much for your help when I was installing this.

One of the worst experiences I have ever had trying to get this installed on a 350 in a Jeep. Spent far too much time and I don't think I ever did get it running right. I tried to talk my client into a multi port system from another vendor, but they insisted on this. Sad thing is, they've never been back. I'm sure I lost a client over this EFI system.
