I've got a towing tune coming together. I build a base tune from my economy tune. Tweaked it for use on my Jayco RV which is 31 foot long and typically scales in at 8,000 to 8,500 pounds. 

 

As for today I was using my BigTex trailer and headed back down to Middleton, ID to put up my free bed. King size, dual zone adjustable. I had a 1/4 tank and left made to Council, ID and got 30 dollars of fuel (5.6 gallons) and continued to Middleton, ID loaded up the bed and headed out grab 20 dollars (3.8 gallons) of fuel and continued back to Payette, ID. Basically traveling 100 miles on about 5 gallon of fuel. Trailer was empty down (1,800 empty weight) and loaded no more than maybe 2,000 trailer and any other cargo in the truck (maybe an extra 100 pounds). When I was at Payette I got 100 dollars on my Maverik Nitro Card gives me 6 cents off a gallon so it was 20.004 gallons at $4.999 per gallon.

 

I changed up the timing and it builds boost quicker, holding on and grade it might bump the added fuel zone little bit but it falls back to my stock fuel zone pretty quick. EGTs are cool, even on a 7% grade no more than 900°F at 65 MPH. Tune is smoke free, launches good with a load, easy to build power. Even wide open I struggled to even get close to 1,200°F even on the grade passing. Just cruising on the Interstate at 80 MPH (2,450 RPM) I was just about 750°F.

 

This is just my first setup but I'm planning on heading to California with my RV so more tweaking will be performed. Just for the first run I'm very happy in the power even though I'm only using level 3 (CANBus fuel only).

 The added weight of the rv may result in some tweaks just to keep the power where you want it. 

 Did you get any sort of mpg reading while towing the big text? Kinda curious to see how this works out. 

 I may have to spring for an adrenaline after all.....   

Roughly 20 MPG with the light weight trailer (calculated guess).

 

I'll be heading out on the 9th and running fully loaded on the RV to Cally. I'm going to be fully loaded, water, propane, clothes, ATV in the bed of the truck.

Will this tune be offered for sale soon? 

 

New member here in process of swapping my 50hp DAP's to 100hp and going from Edge EZ to the Quad ADR sitting here in my office. I want an economy tune (shooting for over 20mpg on my daily 50 mile highway speed commute) and don't need off the line power but what I call "slingshot power" for passing that slow farm truck that is doing 53mph in a 75mph zone. I'll also want to purchase a towing tune for towing my 8000lb 5th wheel here on the west coast where I can see elevations from sea level to Tahoe in 90 minutes of driving. 

100hp DAP injectors (8 x 0085)

Yay, someone else with those injectors! I bought mine months ago (or a year and months ago, can't remember) but still haven't installed them.

Soon. I'm going to finalize the tune on my trip to Cally. I'll be packing up today and heading south to Parma. I'll monitor and tweak the tune as needed.

I had purchased some used Bosch's for cores, then decided to buy the DAP nozzles as they seemed really cheap (odd hole count maybe?). I took all the components to the local fuel inj shop, had them go through the injectors, install the tips and pop them at 310. 

Well the tune has a small problem with the fuel map. Did a modified version of my normal empty tune. I've see what I've got to change up and have a solution. What was happen start yo ramp up on the upper power band over accelerater and then sag back in the stock fuel zone. Never fear I've got an idea for solution.

Did you ever figure out a solution? I'm fixing to make a 15hr drive to North Dakota pulling a light empty trailer and am looking for a good tow tune.

Last few tweaks if done do pretty good I could release this tonight and let you test it out too. I'm set for power above 10 PSI of boost. I'm not running any wire tap mostly level 3.

Did this tune ever become available for purchase here on the site?

It's in the tune section.

So is the "economy tune" the one recently dated Sept 5th? I was thinking that there was an "economy tune" and a separate "economy towing tune" as described in this thread. 

 

thanks for any clarification! 

I wish I had more trailer time to test. I've only done the trip to California but I had high wind the whole trip. Mostly about 8 to 9 MPG because of wind.

 

The only other time I've tow my trailer was up to Burgdorf, ID but never got a MPG. Also all up hill.

 

So there is no good data to say it actually economy tune.
