My dad had an 07' FJ Cruiser with the 4.0L and 6MT that I drove quite a bit. It was kind of a dog at lower RPMs too, it liked to sing.
- @Nick1994 : The 3.5L is OK, They say more efficient than the 4.0 (I never drove one of them to compare myself). The truck no doubt is not in any way fast. But it is fine by me above ~ 2,000 RPMs. Above 3,500 RPMs it sings, but that takes a conscious effort that I am still not used to. Personally, I do not care for the tune. (It has both direct and port injection that phase in and out based on some crazy matrix). I would gladly trade 20% off the top end, that I VERY rarely use for 20% more torque on the low end. From ~1,600 to ~2,200 RPMs it is a dog
