Those boost numbers are correct within 0.5 psi. I get spikes up to 21.7 psi on 93 v.101 and it settles around 20.5. The torque figures your AP puts out are a load of crap as Colin said. It's all based on sensors and don't tell you what's going on at the wheels. Even dynos can give you some wonky numbers as no two are identical in calibration. Mustang vs. Dynojet has been raging forever as to which one gives true readings.
Some prefer one over the other and there really is no clear winner. The best thing to do is stick with one type, make a few good runs, i.e. go a couple of times but try and keep the same parameters (same basic temp, barometric pressure, altitude) and average your best runs from each session to discover the most accurate numbers.
I really doubt anyone is pushing much over 250 at the wheels with Stage 1 at this point unless they've made adjustments using AccessTuner. Intakes, exhausts, and FMICs all help a little at this point but until Stage 3 and Pro Tunes are available, the power increases will not be mindblowing. Keep an eye out on what ATP does in the near future...the key to unlocking shocking power in our cars will be a turbo upgrade due to the lack of flexibility inherent to the KP39.
Also, cams will be another big step and something I look forward to bigtime. I have no clue how much our stock internals will be able to deal with but forged bits will probably be needed above 300 whp. Look at the British WRC teams running Fiestas with 1.6 blocks. It's do-able but serious attention needs to be paid to strengthening the oily bits.
There, I've spoken my peace now no more silly talk about "well my AP says I'm putting out THIS much torque!"
