My Results Using the DiabloSport Trinity Programmer
Well my DiabloSport Trinity tuner showed up yesterday so i immediately got to work setting it up. after downloading the software on my computer and updating the tuner, i plugged the thing into my SS and set it to the Performance 91 Octane Tune with a couple modified parameters. the things i modified were turning the DOD (Active Fuel Management) and Speed Limiter to OFF. i then drove it around the block a few times and began to notice the difference in power. the throttle response was more noticable, and i actually heard the tires screach for the FIRST TIME! it's hard to imagine a 400hp car that doesn't burn rubber off the line, i guess those pirelli's really do work! anyways after a good 30 minutes of break in, i began to do some 0-60 times using the drag simulator that is on this programmer and here are my results:
Completely Stock Average 0-60 time (3 pulls): 5.1 seconds
After Tune Average 0-60 time (3 pulls): 4.9 seconds
That's 0.2 seconds faster off the line! I did some math (thank you college) and that's equivalent to 18hp at the flywheel, 15 hp at the tires assuming 15% loss of power in the drivetrain.
Now i know what your thinking, 5.1 seconds stock? the factory claims 4.6! well i'm not a professional drag racer, and where i live the streets aren't perfectly flat. there's hills and traffic and LOTS of cops, thats why i didn't run an 1/8 or 1/4 mile, too dangerous. but i did do the times on the exact same street from the same light every time with minimal traffic.
Also don't take my horsepower readings as an official number, i calculated them, they're not dyno numbers, just a difference in horsepower of each calculated case.
Another note: if you do decide to get one of these guys, there is a free program called DSLogRedux that lets you import logged data from the tuner and it analyzes the data and tells you what parameters to modify for better cruising MPG and WOT performance. do that with a Hypertech! for more info on it, read the forums at diablosport.com. i already ran this program and i have the modified parameters i will be testing this evening. i will post any new times i get if it improves!
Also, if you have already modified your ride, this tuner is fully compatible, just run the DSLogRedux with your log results and your car should be completely dialed in. if it's heavily modified with LT headers, supercharger, nitrous, cam, etc. then what you can do is install your desired tune into the car, import the tune onto your computer, and DiabloSport CMR Experts will create a CUSTOM tune for these mods! what other power programmer does that?
so if your interested in buying this product, go to DiabloSport.com and check out their promo ad on this product. i guarantee you won't find better customer service and feedback with any other programmer!
