I have been working on a 1978 Landcruiser with a 1uz. Well the rego says 1978 but it's made up of a few years of parts like many older cruisers these days. Fitted with an early 1uz that I wired (whole vehicle) a few years back. I finally got to take it to the dyno. Its running a link G4 with a prado auto(70 series). I dropped to some 31/10.5x15 wheels for the dyno runs. As I was reasonably happy the tune was safe I did a power run straight away and it spun up 121rwkw. I then removed the airbox as I suspected it was an issue and without making another changes it spun 144rwkw. The dyno sheets show the first and second runs. I then continued the tune and ended up happy with 155rwkw. It drives heaps better and goes quite a bit faster then a landcruiser was designed to go.
