I am posting this in general because a lot of folks are wondering about the InTune from Diablosport (which I installed with my Airaid CAI on Saturday). I got both of these from Autoanything for $509 shipped. A steal to say the least.
Airaid CAI Install impressions: I am hardly an advanced mechanic, but not a novice either, I have installed an entire front mounted intercooler setup and fuel upgrades in my driveway (just to give you a guage of my skill level). The directions for the Airaid CAI kit were probably among the best I have seen for a bolt on piece. No "find xxx part and remove" sort of directions. Plenty of detail and pictures. Most of the assembly for this kit can be assembled before you even pop the hood with basic tools. Just make sure you have a torx set handy. Took me about 30 mins to install, with the only hang up being the coupler going on to the throttle body (use some lube and another set of hands if you can get them) and making sure the air inlet was lined up. Otherwise pretty straightforward. I am rather impressed though that they had enough sense to include a good piece of weatherstripping with the kit so that it seals (with me it is the little things that make a kit more quality in my mind). After the install, I fired up the engine (before I installed the InTune) to make sure everything was functioning normally. Sounds a lot more growly than before. Stepping on the throttle produces a noticable whistle (almost turbo spool-esque) noise. So far so good.
Diablosport InTune: To be honest I was a bit befuddled when I opened the box and tried to turn the thing on. Where was the power button? Well it didn't take me too long to realize this unit is completely powered by whatever cable you have it plugged in with (just thought you guys would find that funny)
. Plugging it in to the computer instantly got the unit into the update process. I did get several onscreen warning from Windows 7 that there were no drivers, yada yada yada Admin mode yada yada, ignore them. The unit still updated itself no problems, it did take a while though about 25mins or so. After that it asked me to register the unit with the vehicle. Had to select 2012 (2013 not on there) but I doubt it mattered. Once the Airaid was installed and I ran the car a bit, I plugged the unit (which looks like a small Ipod) into the OBD2 port and selected the tune option. One thing that I do like about this unit is that the interface is pretty idiot proof, and so is tuning. You just follow the prompts and adjust or answer whatever question it asks. I just installed the canned 93 octane with no adjustments, but there are plenty of things to adjust if you are so inclined. Touch screen wasn't the most precise but plenty usable. After about 15-20mins and about a half dozen ignition key cycles, it was ready to roll. And now the fun part.
Driving impressions: Money well spent.
The combo has a NOTICEABLE increase in the power band of the motor. Out of powerband I can't say I honestly felt a difference (mind you this is the non adjusted stock 93 octane tune) and this isn't scientific, just butt dyno. The sound, oh the sound! Glorious. I referred to this car as my growly fun-mobile after getting out on the road with this thing. The vehicle felt so much more lively. Some had suggested that they felt the throttle was a bit more touchy after installing the tune, I honestly didn't feel much change in throttle response time, just simply in the amount of power when you put your foot down, and the engine sounds noticably more...beefy, even my girlfriend, who isn't a car person noticed when we went out to dinner Saturday (and I wasn't even really getting on it). Hopefully some time soon I will have some dyno numbers to show for it. But the sound of the Airaid alone was worth the money (debate still abounds if the CAI produces any noticable HP gains by itself), the tune DEFFINATELY worth it. I like the interface and the easy to use aspect of the InTune. It has plenty to offer when I get more funds to do more to the car. I was originally going to get the JLT CAI unit, but for the price I couldn't pass on the Airaid. No regrets. Fuel MPG was down a bit...
I am curious to know if fuel economy on the freeway goes up (per the claims of both units). I drive 100 round trip every day so I will post if anything is noticable on that front when I get some more wheel time. If anything, my money made the car so much more entertaining (not that a 300 HP car was BORING to begin with....). Well worth it.
