Have there actually been cases of peoples motors blowing with a 3.4, intake and dp?

I know you are all helping me, however from my father's experience with his car running a worse setup than I, in the same condition for 80k miles i think i can get away with 100 miles in less than 1/2 throttle.

Im not sure if a tuner or off the shelf tune would be best for me.
I feel like i would just download the dhp file, then leave it alone in fear of messing something up.

Is the reason i cannot stay below stock boost levels because it will get into boost at lower rpm?

thanks
