Took my 07 4runner in for a Nav system install today. My runner has but 1457 miles on the odo. The loaner they gave me was a 07 also with a bit over 5k on the odo but had a LOT more power plus the tranny shifted a lot quicker and smoother . Did you guys notice a power increase as your trucks broke in? Just curious and a bit disapointed now in mine, not that there's much I can do about it.
