just put my genV on to my genIII IC setup... noticed my rev is high and iac reading 185.... did some driving testing it out a little and cruising is normal but went WOT a couple times and noticed only 4psi of boost and threw these codes on the last one...

P0122
P0243
P0300
P1120

I know what the codes are but not how to fix them...

I went from a genIII with a N* to genV with LS1...

im thinkin maybe i didn get that ***** sealed good enough :/ but i dont get what would make everything else be weird...idk...ideas?
