back to the issue of how much there cam gears suck. My freind on his LS had a set of the AEM's, and when he went to adjust them, ever bolt had striped. Then he got his easy-out out (lol) and tried to remove the bolts. All that did was ripped the bolts to peices instead of griping them and removing them. Why is this? AEM's bolts are extremly shitty. They could use playdough and it would be harder bolts. He later replaced ever bolt with some good grade 8 bolts, and now he hasn't really had any problems.
No matter what brand you have, put locktite on the bolts, and check them offten. Pill_PMD had the Skunk2 gears, and had them slip on him because the bolts lossen up.
