DTC P0172, P0175 after two days boosted
alright I need some help until my tuner gets back with me. Like the title says I installed my SC and after two days and less than 50 miles I get these codes with a check engine light. Is it safe to drive? I'm thinking its just the o2s since I have cheap cats and LTs for inspection purposes. I had them "tuned out" before I programmed it for the TVS. What do you guys think?

p0101 is maf related...it may be dirty or maybe got bumped during install? I have gotten it on my 8.1 a few times, but I think my issue was I was overflowing the maf.
Let Justin see the logs, I would bet it just needs a tweak here and there...you can def. drive the truck with those codes..''shouldn't'' do any harm, just won't run to its potential.

yea Justin looked at the logs and the injectors were just spraying too much fuel so he changed the tune and it runs like a dream again. I'm going to pick up some MAF cleaner today and make sure the intake is clean. I also have to re torque and loctite the intake bolts because they losen up after every drive

which part the tuning or the intake bolts? If its the tuning every engine is a little different and like a lil of this and a lil of that better then the next and Justin does exellent work. If its the intake bolts mine and Prestons both losened up a few times but then settled in and I havent had any issues after retorquing them the third time. Maybe the othe TVS guys will chime in but its ok thats why your supposed to take it easy at first so you get all the bugs without blowing anything up.
