Thank you for your interest in a custom DiabLew Tune for your GM vehicle! My custom tuning is for GM vehicles running 87-89 or 91-93 octane gas (no E85/LPG). Custom tunes are created specifically for YOUR vehicle, with adjustments made based on real-world driving data. Afterall, your vehicle is as individual as you are... Tune it that way!
Using DiabloSport's CMR tuning software, I am able to customize parameters available throughout the entire tune file, and am not limited to just the preset parameters available to you via the hand-held Predator, inTune, or Trinity interface itself. Some changes include timing, fueling, throttle settings, knock retard, spark retard, torque, torque management, DOD/AFM, etc.
With the custom tune, you'll gain even more HP/TQ, even better/quicker throttle response & acceleration, stronger/harder pull, smoother & quicker power delivery throughout the rpms, etc. By providing me with real-world driving data logs throughout the tuning process, this ensures that the custom tune is tailored specifically for YOUR vehicle setup, fueling/timing is adjusted appropriately, etc. More...
As far as gains go, absolute HP/TQ gains are hard to predict. Every vehicle is different, even if they're the same model, engine and have similar mods. Location/weather, fuel used, elevation/altitude, etc. all play a role. The same holds true for mileage gains - those variables, plus driving habits/style, how much highway vs. city driving, etc all make a difference. You could gain no MPG increase, or you could gain up to about a 3 mpg increase - tough to say due to all of the variables in play - so there is no guarantee of any specific amount of hp/tq or mpg gains.
With the custom tune, I can tell you that you will definitely have a very noticable performance difference/gain over and above the preset canned DiabloSport tunes that come on the programmers.
I have gained people anywhere from 12-39 hp, and 10-23 lb/ft. torque, and 0 to 2 mpg - above and beyond what the preset canned tunes give you. Again, obviously mods, fuel used, etc. all played a role in who gained what.
For all of the custom tune work and multiple data log analysis that's performed, I ask for a reasonable fee of only $135 (USD). This will cover getting your full custom tune dialed-in and finalized, as well as any future tune re-adjustments for a period of 1 year. After the 1-year period has passed, tune updates are just $75 (USD) and that would cover you for an additional 6 months. (Restrictions apply: I do not do my email tunes for turbos, superchargers, medium/large/wild cams, etc.)
Custom Tune – $135 USD
Custom Tune Info / Instructions:
After purchasing the custom tuning, then you would need to send me the necessary files I need in order to start working on your tune for you. I need copies of your "original backup" and "last tune written" tune files, as well as a steady driving data log.
Follow the set of instructions below that applies to the DiabloSport programmer you currently have:
1. – If your Predator is a U7198, U7193 or U7192 and it is on the newer 9rXX revision:Click here
If your Predator is a U7198, U7193 or U7192 and it is on the newer 9rXX revision:
Then you'd the data log and tune files, and I can usually have the initial custom tune done and sent back to you within 24-48 hours.
If you do not yet have a DiabloSport inTune or Trinity programmer, I am an Authorized DiabloSport Dealer and have them readily available for purchase as well, as you can see on the right!
You can purchase just the programmer itself from the right... Or, if you're also interested in a custom tune for even more/better performance, I offer package deals for them that include my custom GM tuning at a reduced rate so you'd save $$. Click here for package deal info!
The DiabloSport inTune is the successor to the Predator. The inTune has all of the famous pre-loaded tunes and available adjustments as the Predator – in a smaller, more advanced and easier-to-use device! In addition to the inTune's extensive GM vehicle support, it's loaded with additional features not previously available in the Predator, such as TCM/tranny support, support for external gauges like a wideband, etc. All this, plus the ability to get custom tuning done for it and your vehicle!
The DiabloSport Trinity is one of the most advanced devices of its kind, featuring full re-flashing/re-programming capability, advanced data acquisition, and customizable gauges – all displayed and controlled on a color touch screen. In addition to the Trinity's extensive GM vehicle support, it's loaded with other features like programmable shift lights, multiple gauge displays, virtual drag strip, and live data logging. All this, plus the ability to get custom tuning done for it and your vehicle!
I am also an Authorized Dealer for Cold Air Inductions, Inc. intake systems! After having owned a few of their systems for my own vehicles and becoming totally convinced and impressed with their quality, workmanship and performance over the past 6+ years I've owned them, they are one of the best intake systems out there! Quality welded construction, insulated air boxes, ceramic-coated intake tubes, you can't beat it! Click here for details on intake models for your 2004+ car or 2007+ truck!
