go to radio shack and get an adjustable potentiometer. get one that runs from say at least 200 ohms to 1kohm. make sure it is not one turn stop to stop. a multiturn unit will be much less sensitive. then remove all your other resistors and put this in place. using a digital voltmeter, adjust the variable one to where your previous max resistance was. then slowly add more resistance until it runs right for you. then measure the resistance and put a fixed resistor(s) in its place. i ran with one before, but the engine vibration changed the setting and it jumped around on me. when i found where it worked best, i replaced with a fixed resistor.

something else to note... with 30# injectors and rrfpr, you will be rich from about 3000 to about 4500-5000 rpm under wot. so if you run it hard and shift in this range, you will retain unburnt fuel in the engine and the result will be rich running. the o2 sensor will pick this up and attempt to compensate. when it can't, it will go into limp home mode (i.e. ~1300 rpm). just a fact of trying to get more fuel into the engine with the stock ecu... hope this helps...
