OK I put the kit in and being a van it did cause some frustrations with the small engine bay. Nothing much more than having to take out lots of stuff to mount it, but easy other than that.

I'm pulling a Haulmark 6' x 10' trailer that is 6' high inside, weighs 1100#'s empty, 2200#'s loaded. It does stick out above and to the side of the van and feels like I'm pulling a parachute. It can drag mileage down to less than 9.5 MPG and won't hold speed on grades. Most mild grades will drop it out of over drive for the entire climb till I crest the hill. We are talking Ohio & KY with mostly mild hills of 10 to 20 degrees. This is a 98' 5.4 L Triton, pig of a motor with only 225 HP and 190#'s of torque at near 4K RPM. a completely stupid design for a road vehicle. Just awful for a truck!

First trip to Mid Ohio I had a 5 GPH nozzle and it did pull harder at higher RPM but at loads before down shifting it was overloaded from the injection volume. Ran great at over 73 MPH and down shift runs were shorter. Gas mileage about the same but more power, torque.

I decided I was cover charging it and installed a 3 GPH nozzle, adjusted the controller to come in sooner when the engine load started. It pulled MUCH better, down shifted for only short periods and I still got acceleration up grades after it up shifted. I could hold speed much better. I had started off with 80 miles on the full tank so not much accurate feedback on highway mileage. Stopped for gas 70 miles out from my destination of mostly very hilly and curvy state road. Lots of slowing for turns, traffic and hills in southeastern Ohio around Cambridge to Stuebenville. IT pulled real well both ways and when I filled up on the return trip before getting on the highway, it had got 11.5 MPG on this 140 round trip. Same type of roads, some worse than my Mid Ohio trip two weeks earlier where I got 9.3 MPG. Success!! The run home on the highway was even better than up as I had played with the settings more and I did 200 miles on half a tank of gas. I didn't fill up when I got home so not sure what I got for mileage but it is in the area of 11.2 to 11.7 MPG. This is at 72 -75 MPH. I'm happy with how it has worked. I have not done any trips without the enclosed trailer to see what it does, best I have got that way, w/o injection, is about 13.5 MPG. Used almost 4 gallons of washer fluid over the 540 mile trip.

I'm running off the washer fluid tank with only a gallon capacity. I'm going to have to add a reserve to pump into that tank to go the total distance a 33 gallon tank will run. I used -22 washer fluid and spiked it slightly with denatured Alcohol. I'm going to need to also find a cheap outlet for 30% fluid or buy alcohol and distilled water to mix my own.

I have considered adding a second nozzle at 2 GPH that would kick in at higher RPM and throttle openings for more punch and MPG.

Now I think my daily driver needs a boost. 2003 IS300....
