u will see where throttle peice goes to the injectors there are 4 bolts there take those off there usally are 2 springs there which make it go to the 3400 or 3900 rpms, also if u want fuel delivery faster or slower this is done with shimming the injectors up or down these shims are .001 to most likely ten thousandths, most likely take out shims more fuel add shims less fuel most likely or vice versa, it is that or the other way don't know for sure but thats how it works, hope this helps

I'd make sure the injectors have a good spray pattern and you have good compression before messing with the pump. If you screw up the pump it'll cost you to have it fixed. Also just check the RPM the linkage just maybe worn or out of adjustment.

As stated, check your injectors and compression first. The idle and max speed should be factory set and really shouldn't need to be adjusted.
Injector timing is done with shims, you work it all out with the front pulley and the FI mark. You can work out the angle and add or remove shims. This is also factory set, the only time you would need to change it is if you replaced the pump.
