Make my S900 faster!

Hoping for a bit of experience from the guys who have been there, done that. I have read 4,000 different forums looking for solid answers.

Have a 2015 S900 for about a year now. Put on an R2C air filter to help it breath, an HMF slip-on to help it exhale and a Power Commander V with Auto tune to help it clean up everything in the middle. But overall I feel almost no difference over stock. Not looking for top speed as much as bottom end and get up off the corners in a big hurry.

Friend mentioned Clutch, but I read often that the stock clutch is just fine? Will I see a big difference when I get on it? Rest of Rzr is pretty stock (tires etc.)

Is the bullydog a better option then my commander?

Does anyone make good tunes for the commander that will increase over the auto-tune?

I am trying to talk myself out of either Turbo this thing and loose any reliability or selling it for a new toy that’ll get up and go faster. I don’t need 90 mph, I want that force yah back in the seat 0-60…

Thanks in advance….
