One of the big advantages to the era of turbo Hondas is that there's plenty of horsepower and torque left on the table for tuners to take advantage of. One of those companies is Hondata, and following its upgrades for the Civic and Accord, it's now tuning the Acura RDX luxury crossover.
The RDX uses a turbocharged 2.0-liter engine similar to those in the Accord and the Civic Type R. In stock form, it makes 272 horsepower and 280 pound-feet of torque. With Hondata's Stage 1 tune, the company says that horsepower increases by about 10 across the rev band. Looking at the dyno graph, it also appears that peak horsepower increases by about 5 horsepower, and peak torque is up by about 15 pound-feet. Peak torque also appears to arrive sooner, and most of the torque curve seems to be up by 10 to 15 pound-feet. The increases in power and torque are available in all four of the RDX's drive modes.
The Stage 2 tune increases power torque even more in Sport and Sport+ modes, and keeps Snow and Comfort modes at Stage 1 settings. Peak horsepower looks to be up about 10 over stock, but the mid-range sees as much as a 28-hp increase. Peak torque sees a huge jump of about 45 lb-ft over stock based on the dyno chart, and it's available even lower than the Stage 1's peak torque.
If this all sounds good to you, you can order up a Hondata FlashPro computer for your RDX right now. It costs $695 and comes with the handheld computer for uploading or removing tunes. RDX owners in California should note that neither tune is currently CARB legal.
