I called and talked to Tim at PTC to get his views on gears an with my combo and useage. An he said quite frankly the performance differences from a 3.23 and a 3.55 are very slim and would be hardly noticable but the rpms on freeway would be more of a noticable thing and he said a nice 3.36 would be good as would a 3.42 and would probably go with whichever he found the best price on.

3.36 gears equal 2822 rpms

3.42 gears equal 2872 rpms
