Any dyno tips.

I saw that it was a 90 Mustang and didn't read the speed density part so I assumed he had a MAF sensor. Adaptive strategy still applies, though. The computer only bases its decisions on readings from the MAP (manifold absolute pressure), ACT, and ECT sensors which is why speed density computers aren't that desirable unless they are completely programmable. Feedback is still provided by the O2 sensors.

You're correct that fuel pressure can be used to make injectors provide more fuel at the top end, but without even a cam change, I wouldn't worry too much about exceeding the limits of the stock injectors.
