    Default 06 tbss e40 hanging throttle after ls2 car tb swap

    truck is a 06 tbss awd with a e40 and i just installed the ls2 car throttle body and ive copied ove all the tables for the tb area ect from a e40 ls2 car and it has taken care of most problems, but i had to take so much air out of b1829 min idle airflow to get it to idle back down to 750rpm and if you free rev the truck it will stay up in the rpm ie 12-1500 rpm for 2 sec or so before it comes back down like it has too much air, the truck is in olsd right now also it now logs show the tps going to 83% vs the 88% wot with the old tb, ive heard people having issues with the blade not going all the way open and short shifting after this tb swap and there is a fix i just cant figure it out

    thanks
