I hate to admit this but why is it called BOMBING? Secondly what is better to do regarding warranty EZ or injectors? Do they both leave a trail in the computer if they are switched out? I havethe 7/100,000 warranty but would like a bit more zip. A friend of mine said his friend works for Cummin's and valve adjustment and small computer changes will get you 50 HP. Any truth to this? Sorry I know this has probably been beat to death already. Thanks!
