TOrque- ur a champion.
you also mentioned the diff.... what sorta indications should i look for which may tell me that the diff would be coming up soon?
Sorry for the noob questions lol... just starting to learn abt them
If your having issues turning slowly or turning in reverse or you hear some groaning in reverse then your having center diff issues. My last DD STi had a bad center diff and I was tuned at 309hp I dont know what the previous owner had done since it had broke before I even bought the car.. But I think that is pretty uncommon at that power level.
