    What am i missing???!!!!

    i just upgraded to 1 bar sd, i cant seem to get the rtt feature working, but i feel like im chasing my tail with this tune!!! it seems like as soon as i give it what its asking for, my afr will go in the opposite direction, or my idle will fall apart.... im sure its my fault due to my inexperience, can someone thats smarter than me take a look???

    its an 02 camaro ss m6
    just installed a 227/234 115 lsa
    obx lt's, resonators and slp cat-back
    comp cams double valve springs
    slp lid with bellows
    melling oil pump
    rollmaster timing set
    ls7 lifters
    stock 241 heads
    ls6 intake

    to be a little more specific, the car wants to stumble on itself at low rpm's when i give it atleast 1/4 throttle. wot seems to be consistant around 13.2. and at steady throttle in any gear the car lerches almost like it was missing, but im sure its not...

    still acting the same.... it takes quite a while to find idle after coming out of gear (clutch in) it will drop to about 3 to 400 rpm and sometimes stalls. once it finds idle it seems pretty smooth, i have used russ k's idle cfg numerous times and it doesnt ask for any changes. have tweaked with idle timing and it still struggles. ve and pe tables seem to be damn close but it still lerches with steady throttle in mid to low rpm's. this happens using both the sdbase, and sdtune files so i know im missing something, but i just cant seem to figure it out!

    ok, i messed around with olfa and it seems to have helped the searching idle a little, but im still not seeing any consistant numbers while trying to tune my ve... It also seems to lean out really bad at random times at idle. anyone??? please?
