Default 2 Tech Questions

First off there is an extremely annoying whine when I accelerate my car. I can have it in neutral rev it up and no noise, only when in gear and with foot on the gas any ideas? Also I had it professionally tuned was going to sell car took off injectors 42lb and put on stock for a day, but changed them back once the check engine lights come on. I was wondering do i need that custom tune again or would I just need a shop to pull up the tune already that is programmed? Only thing is I can tell its a tad bit sluggish and check engine lights come on and it never did it before and was tuned to not have catalytic converters which is a code its throwing thanks.

Yes! If you change the injectors you MUST change the tune!
