ordered a vibrant vacuum block, going to install it on the brake booster line and run a few things off of it... wastegate, bov, boost gauge, and ssafc. dealing with 2 CELS, p2006 and p0421. for the 0421 i think it will change once i install the wideband sensor, so i'll deal with that later once its installed. for the p2006, i will try toe vics/vtcs sensors first to see if that fixes it, but i think the problem is with the wastegate actuator and the open/close flap on the exhaust housing. since i had to replace the chra, it is slightly off from stock alignment. i think that this is causing the tab to sit in the middle in resting position, and it will open but can not close all the way. maybe it is the other way around, have to check. everything else is running good so far though. i dont think im at my full boost level yet, due to the wastegate problem, but i can definitely notice some more pep. cant wait to get the vac block and install all my gauges
