My last oil change that i did, i saw 2 or 3 microscopic flakes of metal floating in the top of the oil... ...So, does this mean that i need do a bottom-end rebuild before i even think of boosting on my stock engine?

Or would it be okay to boost a small amount on stock, after making sure that leakdown/compression tests are good? By small, i mean 6 - 7pounds on a t25.
