2004 Gtp tripped a bunch of codes after a full write tune

It's a 2004 GTP that I tuned recently. It had a couple things wrong with it like a vacuum leak and a couple other codes. I tuned the pcm today and had to do a full write. I pulled the radio fuse before hand. Then after a while of driving 10 codes popped up.These are all the codes, p1518,p0030,p0201,p0202,p0203,p0203,p0204,p0205,p0206,p0243,p0443,p1518.

Could the tune have caused this or is there something else going on. The codes are 02 bank 1 low voltage, all of the injectors have low voltage. Then the other codes are for the bbv, evap, and throttle. And ideas guys?
 


being it got codes after the fact, maybe. id try another flash. maybe a partial. or just put it on auto.

best to build a off board for the 04 cars. the newest one listed in the how to section worked for me not to long ago.
 
Are 04+ cars just weird? It said it uploaded fine and I waited 20 seconds, popped in the radio fuse and started it up and let it idle. It was working fine. Then later on in the day I get a text telling me that the codes popped up and it won't idle for over 1 minute
