I own a 2007 with a 3.5, I’ve Installed intake, exhaust, chassis stiffners, full front suspension upgrades, rear springs and struts, a fuel setup allowing e85, and wider wheels and tires.

I love the fact of it being a tad bit of a sleeper making more power out of a v6, and am very happy with the added performance. I still think it can handle more

Where would you guys go from here to add horsepower. I’ve considered bigger throttle body, cam, tune, high flow cat/ catless. Thanks

 

I would say your current options are a tune, or some custom boost set up at this point.

 

I'd second this. You say you're set up for E85 - thats just begging to add boost.

Even of there aren't any kits available, i wonder if you can DIY it like the 3800s do - block off the downpipe hole, add a flange to the crossover pipe and mount a turbo there. Pretty minimal fab work (assuming the 60* engines have a similar style rear manifold / crossover hook up to 3800s).

 

rear mount turbo maybe
