Is it normal for....
Sup all,
Been boosting for about 1 month now(stock block) and I'm wondering if its normal for compression to slowly decrease? I had some oil come outta my catch can therefore I did a compression test. Compression was @ 230 for #1,2,3 and 225 for #4 before the I began boosting. I did a compression test last night and #1,2,3 were at 220 and #4 is at 210. I'm just wondering if this is normal for a stock block. Any info or experiences would be greatly appreciated. Check my sig for details on the setup.

Compression loss is not normal 
My compression has stayed the same for over a month, no tuning of any kind, stock injectors, ECU, with a much larger turbo on the same amount of boost. I would do a leakdown test as well.
