r-6

Hi there everybody
I just completed my turbo set up
d15b
IHI tubro at 8psi
front mount intercooler with 2.25" piping
down pipe to muffler 2.50"
management p28 with urberdata
460cc injectors/255lph fuel pump
Heres the problem noticed idling to low adjusted idle screw no help throttle cleaner no help
all of a sudden today drving engine check lite came on
scanned for codes say it was tps/iac/heated o2 sensor
can anyone tell me if they ran in a same problem
How can there be so many things faulty I just don't believe it or can it just be that my computer is done
any input would be nice
Thank you
