Idle problems after inj swap

Idle problems after inj swap
Probably some noob questions here, but after some hours of reading I am not getting closer.
Here is how I got into my problems:
-Removed Vortec and checked that the car was ideling fine with the 1.8 injectors
-Installed the MSPNP and adjusted timing. Smoooth Idle!
-Welded in the IAT bung and removed AFM, new firmare. Still smooth idle
-Then installed my Rx7 550 injectors and made the following changes on REQ_fuel, Acc Wizzard and crank settings:
Rec fuel set to 5.6 after using the rec_fuel function in megatune
Crank PW (Based on 230-550 calculations):
-40f 4.2
-20f 4.0
0f 3.8
20f 3.6
40f 4.0
60f 3.7
80f 3.2
100f 2.6
130f 2.1
160f 1.8
The accelerationwizard hawe not been touched from base map since I am just trying to get the car to idle smooth before I am driving it. The Acceler Wiz is for compensating when you hit the throttle right?
After the 550 install the car idles like its only running on 2 or 3 cylinders...
Have I done any realy bad settings or are the reconditioned 550s i bought with flow sheet from osidetiger.com just not working?

Mine acts like it's running on 2-3cyl at anything below about 10% throttle load, including idle and light highway cruising.
As soon as I roll into gas to accelerate, or hit a hill which ups the load, it runs smoothly.
Takes off like a scalded dog in boost.

My wbo2 sensor not quite good at the moment, I am getting a new sensor for my zeitronix tomorrow... I tried to idle the car again today, it ran a little bit better...
A new question, if you change some settings in the map, and then are going to press burn to ecu, do to have to shut the engine down? Or can i tune and save the settings with the engine running?
