The idle looks good, I take it you seeing the 13.5 at start-up both warm and cold then it runs down to 15 ish?

Cruising is a little on the lean side from my experience 16 is the lowest I will go and 18 is pushing the EGT's through the roof plus the car will be suffering from a lack of torque and response

Boost - Looks good as well, But the 10 is a bit high for the CA gain from my experience pull her down to 11.2 - 11.7 you will feel the improvement in both speed and fuel economy.

It looks like to me that your midrange off boost to on boost zone is lean as well I might be wrong, Once I corrected this area on my CA the car had a lot more torque off boost and made running around town at 3000RPM and below a lot nicer
i bet this is the reason i never liked my ca, but i love my sr! the sr had a customisable ecu, with the ca i never knew what was happening with the AFR's, nor did i have the ability to sort it!

Honestly Get NIStune or a stand alone, Your not going to get any real success by tuning the Fuel pressure and MAF

honestly...

i suppose it is. you've been driving like this everyday for ages and its been fine, right?

then hold out for the nistune. i've worked on an s13 sr20det with dicktator, and an s13 sr20det with gotech pro. and although i haven't seen it first hand, i've seen screenshots and i've heard all about the nistune.

based on what i've experienced, the dicktator is easier to tune than the gotech, the gotech has more resolution, but the nistune is the best complete package (by far). specially if you get the one with knock sensing functionality!
