I'm Awesome
I have a 1994 k1500 5.7 auto 3.73 gears z71 stock engine , stock exhaust minus cat , I would like to get the ecm programmed for lean cruise at hiway speeds as to try and get better fuel mileage. Can i send my ecm out to someone to program or how do I go about this ,Is there a chip I can buy that is a plug and play with no tuning that would do it? I am near Omaha Nebraska if someone can program it there.
