Base Engine Tune

Been back and forth on what to do about tuning the engine. The control pack base tune is adequate for the build but at some point it has to be addressed. The gold standard around here is Lund. Everyone says they are great. They ought to be they charge $1200. It's a little crazy. I looked at a local chassis dyno and they want $850. This was my preference but they want me to drop it off and might take them a 2-3 weeks to tune it.

I found a company (really a network of tuners) called Juggernaut Performance Tuning. They charge for a Coyote w/an upgraded intake manifold $299. I need my own device. I chose the STC X4 I got for a little over $300. I filled out a ticket and told them what I had. They reached out and asked about my transmission and few other details then sent me a base tune and instructions on data logging. They asked me to upload the tune and run it to full engine temp then send them the data. This is what I did



I then setup the data log per the instructions



The engine ran very smooth. They fixed the fan which was kind of awesome. Goes on at 195 and off at 180 now like normal. Still idles a bit high at cold start but very improved. Next is for me to drive it around the block. We will do this back and forth over the next couple of months. I have 6 months to complete the "program". They use a ticket system so I just upload my data when I have it and in a day or two I get a new tune with next steps. So far so good



Lastly I got new shoes!! My youngest daughter held the brake so I could torque the lugs. I'm proud to say she enlisted in the Air Force and is shipping out this summer. Very exciting stuff
