I have a LS3 427 stroker from Texas Speed and am just about to 5k miles and have no oil consumption issues at all. I also made 502rwhp through an unlocked A4. Locked it made 536rwhp. You should easily see over 550 on an M6. I am using a STOCK L76 intake and Stock L76 injectors also. I have been very please with the results I have seen so far. I haven't even switched over to synthetic oil yet. You can check out my other mods in my sig. |
