Hi, my 1uz runs from 0-100 in more than 10s (11-12s) but to my understanding it should be running close to 7.0 seconds flat. I was wondering what i could do to bring back lost power and make it run as good as in the begining. The car even struggles to push at speeds above 110km/h. Seems to have the seem same power from there on. Halfway throttle and full throttle are similar. This vehicle is lighter than the Ls400 which should mean the difference shouldn't be this drastic. I haven't dynoed the car yet as i live about 500km away from the nearest dyno shop. Please help, will greatly appreciate it.
