This is a model from the PPT series, which can be called a standard performance-oriented throttle controller. I used it for about 5 years on a VOLVO V70R, 2004 model, LA-SB5254AW. I installed it because I was concerned about the sluggishness from the start to acceleration in normal mode. After installing it, the acceleration from the start changed dramatically, and I was hooked. However, the problem is that the warning "Engine Performance Reduced" sometimes appears, and the car won't accelerate even when the accelerator is pressed. This can be resolved by restarting the engine. I asked the shop where I bought it, but it seems it's difficult to completely prevent this. I liked the feeling of accelerating from highway toll gates and leaving the cars behind, so I kept using it. The switching functions worked fine until I removed it. However, I cannot guarantee that problems will not occur, so please understand that this is sold without warranty.
