mine does great until 55 or so and after 60 its just pointless unless i wanna spin it at 3k+, seems like if i want to drive on the freeway i have to floor the hell out of it then letoff or do 80mph before the od comes on, i stay on the highways where its 55 cause i dont have $ to put in 4.88 or 5.13 right now. whats a safe rpm for doing 70? i will see what mines at with od off. my cherokee at 70 is 2400 rpms with od on, my 05 is like 1800-2000 and cant even pass someone unless i floor it and it just seems like the motors going to blow, crazy what 33s did over stock, my 05 ranger with 33s i didnt notice much of a difference at all. i wish my jeep moved like the xj, its going to be fun pulling my trailer with this pos transmission this summer. i do have a b&m cooler i still need to get on though.
