you need to look at your LTFT and adjust your injector slope. Make sure there are not any positive numbers on the LTFT. I have mine at -5 at part thottle. When you hit WOT the LTFT should be at 0. To adjust you injector slope, example if you are at +10 then adjust the injector slope -10. Its that easy. You can also look at you what you 02 sensors are reading should be around 900 at WOT. IF its low,adjust the power enrichment up some to get the number up. I would not play with the timing.

Check Diablosport's forum. You may have to send the Predator off for an update to be able to re calibrate the speedo for new gears. FYI

It actually sounds like he is going from 3.73s to 3.42s, so unless the PCM has already been tuned for the 3.73 gears, no changes should be required.
Also, do you know if the PCM has been tuned in the past?, as you should not apply the Diablo tune to a tuned PCM.
