Unlimited Custom Tune Options
We write your tunes specifically for the computer in your truck. You can tell us what that is by reading both your engine and transmission strategies:
To read your strategy, first you need to return to stock tuning, if you are tuned. Connect the tuner to the obdii port in the truck and scroll over to Vehicle Information, press Select. Follow the instructions on the tuner and let us know the VX (engine strategy) and TQ (transmission strategy. This will tell us what computer is in your truck and that is what we write the files for.
We implement the revolutions per mile in all your tunes. That helps with shifting and fuel mileage but if you change tires, you have to let us know as both shifting and fuel mileage will suffer. There is never a charge for updating your tires.
Please take note this is custom tuning. We do not recommend loading tunes on a vehicle, if the files were not written for that vehicle.
Here is a little bit of information about our tunes:
Economy - is designed for bumper-to-bumper traffic to reduce turbo lag. You can save between 2-4 mpg. (40rwhp)
Economy Only - We have found that most people get the best fuel mileage from our Looney tune, as long as they are not always on the pedal. This file is designed in the image of the Looney but does not contain performance parameters. You can save 3-6 mpg. With this file you cannot tow at all. (40-50rwhp)
Transmission Only File - We do not recommend towing more than 10,000, on flat ground and 8,000, in very hilly or mountainous terrain, with a file, any file or anybody's file. This file is the alternative. With the transmission shifting properly you will feel the truck to be stronger (+/- 20hp).
Tow - is designed for pulling. A normal tow file is about 50hp, when aggressive can range between 65-75. We can also add jake brake to any tow file. This feature works with the exhaust back pressure in your truck and you must have your tow-haul on when pulling weight but don't need to turn tow-haul on if not towing.
Eco City- Was designed for people who tow often and/or tow heavy who don’t want to change tunes when not towing. It is an economy/tow type file with 80-85hp and most people find it very fuel efficient. It is also the file we recommend for when it is very cold, the streets are slippery or the weather is just bad.
Street - is designed for highway driving. It's drivability parameters are intensified for ease in passing and maintaining higher speeds for longer periods of time. (90-120rwhp)
Street_pct – This is a new file. Seems to be a little stronger than the Street file and brings the power on more progressively. (90-120rwhp)
Looney - is designed for daily driving. We've been told it shifts better than stock and as long as you are not always on the pedal, you will save FUEL! It is written to give you the most power, for daily driving, will still keeping your gaskets intact. It can be very fuel efficient. (130-160rwhp)
Looney Fuel – is designed for daily driving. It is very similar to the Looney and for some it feels stronger, while for others, the Looney is still the one. Basically we applied parameters from the Looney Wild that provide more airflow, in an attempt to increase fuel mileage. (130-160rwhp)
Looney_pct – Like the Street_pct, this Looney is designed to bring the power on more progressively. (130-160 rwhp)
Looney Wild - 20-30 hp more than the Looney but we only offer to customers with aftermarket headstuds. This is a daily driver file and seems to be the most fuel efficient we offer for the 6.0L (150-190 rwhp)
Looney Wild_pct – Like the Street_pct and Looney_pct, this file is designed to bring the power on more progressively.
Looney Wild Track - Same horsepower as the Looney Wild but you don't need headstuds to run this file since it is NOT a daily driver file. It is only for racing/competition pulling and the dyno. Basically what we do is take away a lot of the drivability to give you more power to the ground.
The above categories can be modified for your particular application. Let us know what you are looking for and we'll tune to your specs.
