E85 Dyno Tune - Complete!

[moretorque05]

I had an E85 dyno tune done 2 weeks ago. The truck is the one in my signature. 3.42's, aFe intake and E85. I had 950 miles on the truck at the time of the tune (owned it about 3 weeks). I took delivery of the truck with an almost empty tank so I could put E85 in the day I got it. That's all I've ever run in it.

 

Power gains were not numerically huge, but it drives so much better. Power is always right there and it just keeps pulling... and pulling. Everyone that has driven it (including two fellow 2014 Silverado owners) is shocked with how quick it is. I've had A LOT of vehicles and it reminds me a lot of my tuned 2004 GTO. Very similar.

 

The shop that did it is well known in the area as the best GM tuner (West Bend Dyno Tuning). Very confident and happy with their work!

 

They put it on their Mustang Dyno. Final results were 323rwhp & 360rwtq. Picked up 20hp under the curve at 4000rpm.

Thinking about running E85? DO IT! (Give it at least 2 tanks when you try it) Thinking about getting a custom tune? DO IT!

 

I am not looking to start an 87/93 vs E85 war or a "high" DynoJet vs "low" Mustang Dyno numbers debate. Just trying to give some info for anyone curious.

 

These are awesome trucks. Get out there and enjoy them!

 

Thanks!

I'd like to see a dyno sheet on a stock 5.3 on gas vs. on E-85. I sure like the way my truck runs on E-85 it seems a lot more responsive than on gas. The price is fluctuating around here, I found and 80 cent difference between two stations this week. I know on trips I'll probably have to go back to gas but for now the E-85 makes my truck more fun to drive.

I am looking for the same thing. I am fixing to start running some e-85 in mine with the BB tune. I know it will be a big increase over stock with gas but I myself will never put it on a dyno to find out how much.

Interesting. I see they saw the engine knock that some of us have been seeing as well.

What is E85? And can I use it with no tune?

[Sooperdave]

E85 is fuel. You have an option for the 5.3 on fuel which in turn creates a nice power boost. Prolly in that owners manual...

You will think you got a tune, runs better. I was running 93 fuel big savings for me.

[Northside]

I'm surprised more people don't use E-85. The power increase is substantial. I understand it isn't even available in some states. I was apprehensive at first, having heard all the horror stories about ethanol causing corrosion and generally being a bad idea. Then I researched it and found that most of the horror stories are just nonsense and there are even guys converting Holley carburetors to run E-85. I found a pre flex fuel Chevy engine had been run over 100,000 miles on E-85, torn down and no noticeable harm due to E-85. It required bigger fuel lines, and a higher flowing fuel pump but this stuff is free horse power. Then I remembered guys have been running alcohol in race engines for decades. The 5.3 has 11:1 compression which means it should run high octane fuel or be detuned greatly to avoid detonation,. It sure woke up my 5.3.

On my first tank of E85 now and like what I'm seeing so far - only problem is that running on it regularly will take me several miles out of my normal commute route. We're moving cross-country next month and it looks like E85 is barely available at our destination. What I'm wondering about is whether the power gains with E85 are better or worse at altitude - will be pulling 8,000 lb TT when we cross the Rockies. Unlike where I'm headed, it looks like E85 is pretty widely available along my Colorado route, but it will still take some advance planning to run with.

Anyone know the science/mechanics behind E85, particularly at altitude?

[Northside]

I run it in Colorado. I haven't been under 5000 ft. with E 85 in my truck so I don't know how it works at lower altitudes, but up here it added power for sure. It just seems snappier and to have given me better throttle response. it took a couple of tanks before I really noticed the change. I'm sure it will help pulling that trailer. It does reduce mileage a bit and towing that trailer will decrease it a lot, so I'd plan my gas stops carefully to be sure I found E 85 along the way. It's available in a lot of towns here, but the vast majority of stations don't carry it.

[fondupot]

I'd like to give E85 a shot, but the only station around is about 8 miles out of my way. And I rarely go that way anyways.

[iCryWheniGoPoop]

Go try a couple tanks fondu. You'll love it.
