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
