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 inTune or Trinity interface itself.
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 rpm's, better tranny performance/shifting, 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.
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 noticable performance difference/gain and improved driveability over and above the preset canned DiabloSport tunes that come on the programmers.
I have gained people anywhere from 12-39 hp, and 10-35 lb/ft. torque, and 0 to 3 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.
TUNING RESTRICTIONS: I do not do tuning to disable any emissions-related
items/parameters/codes. I do not do tuning for turbos, superchargers,
medium/large cams, etc. Tuning service is non-transferable! Free tune
updates are non-transferable! Tune updates are for updating the current tune,
for the same previously tuned vehicle, for the same original owner. I do not do tuning for pops/bangs, burbles, backfires, or ghost-cam nonsense.
NOTE: These products will NOT work on any Hybrid/E-Assist vehicles, nor on most Auto Stop/Start vehicles.

For cold air intakes, I am also an authorized dealer for one of the best cold air intakes there is out there, by Cold Air Inductions, Inc. They have enclosed, insulated air boxes to keep out engine bay heat, ceramic coated intake tubes to reduce/eliminate heat soak, etc.
I have used their intakes for 11+ years on my own vehicles (2006 Monte Carlo SS, 2012 GMC Sierra, 2014 Camaro SS), and their build quality is 2nd to none... their products always fit like a glove, and it's not cheap plastic stuff like others are... Improves throttle response, acceleration, etc.
You can check it out here - CAI Intakes - and select your vehicle from the drop-down list to get the info/details about the model to order for your particular vehicle.
