I just got my sc400 and love it. Ive added Injen intake cut off the cats center cat as well. Oh new plugs, piggy back for the ecu, walborro fuel pump and just added a nitros kit with only the 75 jets in at the moment. Want to go with the 100s or 125 ? Im such a newbie and not much of a machanic. Ive lurked a lot in forums and fell in love with my ride..I feel the tranny don't shift between gears as fast as I would like. I read online where some guy said something about cutting the accumulator wire for better shifting. no one I've ask about this has ever heard of this..Does anyone know if this guy is just full of it or knows something I cant seem to find more about. he said lexus didnt want the rear end to set down while shifting and the accumaltor sensor or what ever it is was installed for smoother shifting...what else can I do for quicker shifting with the mods that I have...Thanks in advance for your help..
