Bag&bus setups there is similar torque/hp ratio, if putting power parts differently and having different ratio car starts to break handling characteristics. On RR/MR cars that ratio really makes lot on handling, different ratio and you have to redo lot of setup to keep car on control. Power Limiter makes engine response somehow "fluffy" (even sound starts to blur), sharpness is gone if using approx 10% or more.That is btw a huge flaw on gt6 tuning, that you can't iron off those power peaks. There should be at least this option via sports computer, maybe three different options. I thought, that I will try to tune power with low rpm turbo and oil change, and then use power limiter. Some cars allow to install exhaust manifold, which - at least in it's description- should give you better response to lower rpm.
