rushy said:3D cost a bit more and are specific to your car and your mods ( no car is ever the same no matter if on paper they look the same). With 3d the car is usually run quite a few more times than a standard remap. He might have ment that you can have more BHP but to the detriment of the drivability and torque. A guy on vectra c had his 3.2 up to 256 bhp on chipped rollers and could have gone for more but the peak power was in a very small band so would have actualy been slower if he increased the bhp. You can have a lower bhp and be faster due to the power being spread over the band if you see what I mean.
Yes i understand, i have a before and after graph from the rollers and the increase of both BHP and TRQ was around 10 right accross the rev range.
