Bully Dog review and MPG question

[jaredking733]

Hey all,

Picked up a Bully Dog GT today for my 2010 Nissan Frontier SE 4.0L.

All I have to say is WOW. Makes quite a difference. Truck feels like it has even more pull and overall power than it did before, which was no slouch by any means.

Been tinkering with it on and off throughout the day. Gave the WOT restrictor a flip to the off position and the frontier will burn the tires from a dead stop. I only did that once, since I'm not one to go hard on a vehicle like that, but I had to give it a try.

Anyways, before the tune, which is the regular gas one since I had just filled up, I was getting 20.5 mpg. 47 miles into this tank of gas, with a mix of interstate and in town driving, and I am currently at 21 mpg, and it's slowly increasing.

When this tank is gone, I'm going to give the Premium tune a try and see how that goes. I've read about some advancing the timing 2 degrees, but I've not ventured that far into it. I more got the Bully Dog for the performance upgrade it offered, but to see what I could get for mpg too.

Anyways, just wanted to drop a line and let everyone know I bought the Bully Dog and am quite impressed. You CAN feel the difference. Probably even more so with the Premium tune, but that will be next week.

I got it at my local hot rod shop. It's called Tennessee Speed Sport in Nashville.

UPDATE:

After the Bully Dog tune, with regular gas, i got 21.5 mpg (about 1 mpg improvement from stock) averaged over a pretty even mix of city and highway driving. Probably slightly more highway though, but not much.

Now, I'm running a tank and tune of premium through it and will report back with the results of that.

Does your leg ever hit the plug in the OBDII port?

Sure doesn't.

I'm about 5'10" and tend to ride with the seat back a little ways though. But, there's still about 4-5" clearance.

Also to add, just drove 30 miles to work, which is all interstate, and averaged 25mpg on just the interstate. Will report back when I mix the in town driving in too.

25 mpg ?! I just came from the Fontana Nissan meet and I was averaging 20 -18 mpg the whole way. I'd sure enjoy some extra mpg's hah

Yeah more mpg is always a good thing, but I've consistently got 20.5 mpg before the tune running regular gas.

So, it's not quite the improvement for me that some of you could see, but still, even if I end up averaging 23mpg 50/50 city/highway, thats still pretty impressive for this truck.

Dont want to hijack I just thought I would add to this thread instead of starting my own...To much excitement that many cant handle if we do that

Previous to the Installation I was averaging 14.1l/100k(16.68mpg). Not great but respectable for 50/50 blend of Highway and City Driving.

Since the install date i have averaged 12.1l/100km(19.43km). Install is 87 Tuned with +2* timing and +50 for idle(sure makes it run smoother in the heat with AC on). The details of my math are below.

I installed the BullyDog Triple April 21, 2012. I have since put 31,529 Km(19705M) On the truck. Odometer sits at 121757Km(76,098M) as of the writing of this. I commute 90km(56.25M) to work and home, 46km of which is highway at an elevation 3900ft. That mileage includes 12 driving days of hauling a 3300lb Tent trailer through the mountains, Temperatures from -29C(-20.2F) to +34C(93.2F). As far as I am concerned this sampling of driving conditions, styles and locations is about as average for me as you can get. Hence my waiting to post this.

I track my fuel use by dividing trip A odometer reading by the Liters filled. Odometer reads pretty close to actual mileage +/- less than i can measure on ODO on my commute, GPS confirmed. I don't drive like Granny but I also don't drive like a complete A$$hole. Best I have done on a tank was 10.9l/100km, pretty much all highway, early spring, 649km on 70.9L. Worst was 17.8l/100km, 365 km on 65L I was hauling a Trailer through the mountains, with 4 adults, 1 two year old, 2 dogs and gear in the back and on the roof(the gear not the dogs).

I put the Chip in hoping to increase my mileage to ease the price of commuting. Based on the above information I would say it has worked. The investment has paid for itself in fuel savings

The performance on the truck is great. The butt dyno tells me that there was a moderate increase in power, off the line it is quicker that is for sure. The feedback options from the tuner are also great. I do a lot of driving, a fair amount of hauling and in varied weather so the information on temps and fuel consumption, give me some peace of mind when in the bush with my family on freaking cold days or freaking hot camping trips.

Hope that helps any others thinking of making the jump
