Looking for input from Uprev tuned with JUST CBE and Intake (stock cats)

any good tuner will not tune for peak hp. they will tune for best gain across the entire power band, and focus on getting the powerband smooth. they will also play with when the torque converter locks up. on my tune he upped it by 20%. i can now feel when it locks up if im in sport mode and i get on it.
in order to make power the shop actually took timing out in the midrange, and modified some other settings on the top end.
also i found out our cars come with O2 Wideband from the factory! there was no need for a sniffer in the tailpipe during testing at all.

just got back from the tune. dynojet dyno
before 243hp to wheels and 216lbs tq
after 257hp to wheels and 224 lbs tq
with the estimated 25% drivetrain loss with AWD and AT, that puts me around 347bhp to the engine.
air fuel is right on target. we tried leaning it out and it actually lost quite a bit of power.
dont have the baseline graph (a/f was all over the place) but have the final pull.

for those interested, most articles i have read say...
FWD: 10-15% loss;
RWD: 10-18% loss;
AWD: 17-25% loss.
additional 2-5% loss for automatic transmissions
My first baseline dyno (found in another post) on stock motor were 220hp and 197lbs/tq
after hypertech and tanabe axle back 227hp and 202lbs/tq to the wheels
so clearly, R2C intake and stillen cat back exhaust helped and tune helped.
