Hello dear, Hyundai friends, Is there anyone among you who likes to drive a XI55 and possibly also screws myself? Since mid-January I have bought this part and am very satisfied so far. Although it is from ’09, when buying (from the Hyundai dealer) had only 65tsd. On the watch. My plan was and is still to pull 3.5 to. For this I wanted to have it chip-optimized to get more torque because it seemed “underside out” very slippery. Until about 1000-2500 U/min didn’t happen much, but from 2500-3000U/min it goes really well forward, despite its almost 2.4 to empty weight. Actually rather untypical for a 3.0L turbo diesel. As the performance measurement then showed (unfortunately no roller dynamometer) the Fzg has neither before nor after the optimization nor even the factory specified power nor torque. Shit. 400€ in the wind and the old software played on it again. Nevertheless, he needs 1.5-2 liters more than before r. Has anyone had similar experiences? And/or even a solution? The tuner said that there had to be something wrong with the engine (oh no). With a turbo speci – Turbo in order but the exhaust temperature probe before Kat is not in the right place. It delivers a constant value of 28 degrees C. For lean 256€ at Hyundai a new order and built in – no change. And Nu?
