Reason i ask is because i tested them with a precise gauge and the Oem has more lift and almost the same if not the same duration . So now im thinking that the stock cam is better !

Anyone know any details on this ?
I also noticed ever since i did the cam swap i lost compression on all four cylinders and yes i did all kinds of checked from timing to compression leak down tests with no luck .

Thanks

If i remember people were saying a mirage cam was like a stage 1 while an RRM was a .5. While you have the stocker out get that grinded professorially and pt it back in. From what I read/remember there isnt much improvement with a Mirage cam
