I'm not sure if there will ever be an Ascent specific throttle controller, but the Injen PT0002 (LEXUS, MAZDA, SCION, SUBARU, TOYOTA- X-Pedal Pro Throttle controller) has been confirmed to work, just in case you didn't know about it.Brace yourself, Nameless Performance is making a strut tower brace for the Ascent. I see a lot of posts in this section regard lifts and 18’s over 20’s, but I actually like the sportiness of my Touring coming from a 5th generation 4Runner. It’s not for everyone, but I’m leaning towards improving its streetability. Not fooling myself that it has its limits, but I feel a strut tower brace will make a big difference and a good bang for your buck without going much further since I already have the lower profile stance with the factory 20” wheels.
I inquired with Nameless Performance about their muffler delete pipes and asked about a strut tower brace and they said they have one in the works. Now I just need an Ascent specific throttle response controller and I’ll be satisfied.
