If you are running the more extreme stock tunes then it shouldn't hurt your injectors. If you are running tow/econo tunes then it's possible that it could. Depending on whose injectors you are running, you can only pull so much fuel out of them, some you can pull more out of then others.
OOOO, your running stock truck programming. I would highly suggest you get custom tunes. These bigger injectors run on a different pulse width and they require more fuel to flow through them. Now I have stage 1's done by Casserly at Full Force, so the amount of fuel that I can pull out of them are going to be different then hypermax, but I would highly suggest getting custom tunes, one so you don't shorten the longevity of your injectors and two so you can actually get some benefit from them. Not just hp wise, but I've experienced less lag when I still had the stock turbo in my truck, but that really can only be helped when other parameters are changed in order to compensate for those bigger injectors.
Edit: In all honesty, there are some other things that I would also suggest adding onto your truck as well to help those injectors last longer. That's the problem with stepping up with regard to injectors, the whole modding ball game changes and not for the cheaper.
i had injectors before a SCT and it worked fine. it did the high idle stick thing around 1000 when i would let off the throttle and the truck would coast while driving.
why don't you want tunes? is it money? or you don't want to pump major hp?

seriously i would not worry too much. when i money come the I would get Eric at Innovative to get those 155 tune perfectly and just how "YOU" want them to be. and i just thought of this. a lot of the custom tuning does change fueling and pulse width and things and i don't even know. but many drive in Tow Haul when you are un loaded but want the torque converter locked.
