F150 Ecoboost Stock Versus Tuned

To the OP, just wanted to tell you about my most recent experience with my tune.

I just completed towing from Tacoma WA, to Anaheim CA. Overall I got 10.2 MPG towing a 6200LB trailer and an overall GCVW of just shy of 13k.

The truck did amazing over all the passes and did not require a single brake application coming down the Tejon pass (Grapevine) To say a tune is worth it, is an understatement. And not once did it approach redline on the downhills.

Temps were all great the entire trip.

I did the same some years back. I did two trips from south Texas to Moab, UT towing my off road Jeep, a RZR, some spare parts, and gear(9.5k total) in my old 5 Star tuned F150HD. Went up to see some fiends in Ouray, CO and then cut across to Moab. Highest elevation was 11k ft and had some pretty steep passes.

Never got close to redline going down, and had more than enough power to maintain all speed limits going up.

I have no problem with it going to redline on descent braking. My bud has a 2012 Duramax that has hit 4500 rpm downhill, stock. He actually talked to an engineer on the Duramax. He said it will safely hit 5500 rpm if it needs to.

It appears that TFL wasn't concerned with the rev's coming down hill. Personally I've not heard good things about 5star tunes, I've heard alot of people have consistency issues with 5star.

Livernois has been a predominately Ford performace shop since they started. They bought one of the very first EB F150's that rolled off the line when Ford first introduced it and they do extensive testing etc on their tunes.

I don't work for them, I'm not paid by them, I'm just an extremely happy customer who has found both their product and their support to be fantastic. Their people are VERY knowledgeable when it comes to Ford engines from my experience with them.

I've done some pretty steep downhill grades with their tune with a 6500# trailer and I've never had it redline going down hill but I have seen better engine braking performance than I did/do with the stock tune.

As for overall towing, I've seen similar if not slightly better towing MPG with the tune vs. stock, but I've also found on my Gen 1 3.5 with the 6 speed auto that the sweet spot for MPG in my particular setup is about 62MPH which doesn't bother me as I don't like towing any faster than that (unless i need to pass someone)

I see average of around 11-12MPG towing at 62 and under. Speaking of passing there is absolutely no issue of putting the pedal down and confidently passing others when needed, the power is just there when you need it and even going up a grade the truck immediately takes off and easily pulls past just about anything you may need to get around.

I am not sure about that. I had tunes from 5 Star, Unleashed, Livernois, MPT, and SSI in my old HDF150 Ecoboost. Some I purchased and some were given to me to review in the old F150 forums I was on. Star was by far my favorite and best to tow with. I never heard a bunch of bad things about them either.

not that hard to keep our duramax from revving that high and it never has on our travels. Probably because we are match very well. Bigger and heavier probably a different story.

I watched the TFL test of this truck tune going down hill and it whipped the engine to over 7000 RPM (way over redline) before it upshifted. No thanks.

The Duramax will also go over redline when engine braking - or would before the ones with the exhaust brake. I don't know if it's a big deal. That said, I wouldn't tune a truck that's under warranty. Just not worth the risk IMO. After warranty - tune the heck out of it. I tuned both my diesels and loved the increase in performance.

Not sure what tune you're referencing but I've not once ever experienced this with Livernois's tunes, they do an amazing job with the transmission management in their tunes.
