545rfe ?s

I think if anyone uses the 5.7 with the 545rfe they should use Hotwire harness. I think the many years they’ve been doing it it is proven quality. It’s ready to plug in. You don’t have to worry about making your own connections or a bad crimp. They stand behind the product and great tech support. You don’t have to spend $$$$ on an ECM. A 2005 truck or Durango ECM can be had for $75. I have bought several for people who needed one. I even tested for them. Just plugged it in to mine drive it around for a while and shipped it to them. I looked into DYI Hemi and thought this is going to control my car if I make a wiring mistake or bad crimp I’ll be stranded or worse. I think a few hundred more dollars is worth my life and my car if it burns to the ground. Just my 40 cents(due to inflation)

Thanks for that post! I just talked to Chris at Hotwire and he offered my an option I hadn't thought of and I think I like the option. My desire is to put a big cam in my stock 03 Ram 5.7 w/545RFE trans. I was looking at using an aftermarket ECU ( so I could tune it myself) which the factory TCM wouldn't work with. He told me I could use an 05 Ram ECU which he would flash to suit my 03, and supply the wiring harness, all for just under $1000. Plus all my dash gages, AC etc would still work like stock (something I'm pretty sure I'd lose using an aftermarket ECU. I could then tune the ECU with HPTuners which I already use. Now the question, do I spend money on the Corvette or hotrod the RAM?
