New STI owner. What to expect from a Stage 1 Cobb 91 Tune?

Just picked up an STI a couple weeks ago and I’m really enjoying the car. Runs perfectly fine, nothing wrong with it. It handles the corners really well, so I don't regret buying it at all, but the stock power delivery feels kind of inconsistent to me.

Sometimes it pulls hard, especially going uphill or coming out of a corner somewhere around 4000 rpm, but it feels kind of flat anywhere else. Gear 2 is consistently very fun, but it doesn't seem to carry into 3 a lot of the time, even when i shift very quickly.
Once in a while I’ll also get a nasty pull on flat ground when I'm in 3 or 4, and other times i don't feel much. Sometimes I have to really coax it to get a proper pull, even in S#.

I’m thinking about getting the Cobb 91 Stage 1 tune for more consistent power delivery, but maybe you guys have advice on how to get a good pull with factory settings.

For anyone running Stage 1, does the car respond more consistently when you get into the throttle?
Thanks, everyone.
