whoever told you that you can run peak and hold 550's without a resistor pack on the ems is smoking something.....you need the resistor pack because the ems is supposed to see high impedance or the circuitry inside will overheat since it has to push out more volts to power the low impedance injectors....the first thing i would do is install the resistor pack ASAP!!!

btw, i have never stalled with the ems and i'm idling at 14.0:1....what known idle problem are you talking about?....you don't need the bosch high flow pump with the ems since you only need to run stock fuel pressures....the stock pump is sufficient as long as you don't try to exceed 70-80 psi or so

your A/F is all over the place...it goes from 12.8 @ 3000 rpm to 10 @ 3700 and then 13.5 @ 7500....you want the A/F to start off at 14-13.5 whenever you are just beginning to boost and then level off to 12.0:1 from about 4000-7500....who tuned your ems?....if you want, i can look at you maps and do some adjustments to make it run a little better...and definitely FIND ANOTHER SHOP!!!
