Help my friend with a tune?

[B8Nate]

well as you all know I have k04 that was paid for installed by previous owner and I'm personally not even sure what tune it is on, its fast enough for me and coming from a 5.0 mustang and a 370z the 2.0t wasnt really supposed to be a fast car! I am pretty sure it's just on the can k04 tune from APR!

But my friend has all the same mods, intake, HFC, full exhaust with downpipe, forge dv, etc etc but he's not sure what tune he should go with! He wants the most power w/o stepping up to k04. I told him apr, unitronic stage 2 should be good either one! because they make about the same amount of power, same price, etc! So it's a matter of personal preference on his end! But I thought maybe I'd get some advice, info, facts, dynos idk something to help him decide from owners of uni, apr or any other not so big name brand tunes with similar mods to see what kind of power they should make realistically, pros and cons of any of the brands! He def does wanna go with the highest "stage" he can go without him having to install k04 which I believe is 2+ from APR and stage 2 from uni, in other brands that aren't so big but just as reliable / improving are welcome!! Just want some pros and cons, hp gains, any additional info / pricing for the variety of tunes on our car.
Thank you!!

APR FTW

that's what I told him, they're the biggest, you can switch with them and that's my k04 brand and tune that came on my car, but I didn't wanna be biased! I've heard pros and cons of uni and apr!
