Default LT REInstall Problems

I just got my Lts Reinstalled yesterday and their backfiring and popping way to much under slight load. at first i thought the computer needed to relearn the tune but it kept getting worse..what do you guys think it might be?codes p0140 and
p0160 are thrown..I took it back to get it checked out but we couldnt figure it out

Ive checked the wires but havent had a chance to check the plugs yet..do you think the car would throw a code for a fouled plug/wire for a cylinder?

Yea thats not the worst of it...the dude was supposed to port and polish my car also which he didnt do so the next morning I told him and he said that his brother was supposed to do it..then I went to cap my cutout he ruined one of the studs by hammering on it..which he at first denied then said he hammered the inside and then blamed on his brother..plus after i told him the car ran like **** he said I needed a tune which he said he never required for previous installs...plus he was sayin the thrown codes are for the front o2s when they were for the rears..I said well then you must of damaged the front o2 in the install he got all pissed and said I was puttin 30 things on him..plus a spark plug was broken which caused her to run like ****...so I changed them all out.eventually he pp the tb I wont say his name but what really ticked me off was not owning up to it right away and gettin ticked at me when im supposed to the mad one..but eventually he tried to make it right ,no biggie
