im new to this forum due to my recent purchase of a IS200 sport Xreg (plus loads of spare time at work!).
I have seen many discussions relating to the adjustment on the VVT-i tuning. i have seen one unit which is the "Power Enterprise CAMCON VVTi iVtec Vtec Cam Controller" but it seems to be only the is300 which is supported along with some newer models.
I havent modified my lexus in anyway so its just a standard sport. just seems a waste of power until u hit 4500rpm. seem like you always have to be driving on the line to benifit. if it was to kick in at about 3000rpm i would find it much better!
im not very technically minded so keep it simple if you can!

I am sure someone with it fitted will answer your questions better though as I have not had one but I did look into various options a while ago.
Welcome to the forum!!

your looking at maybe a couple of BHP but like has been said lower down torque.
if you search for CAMCON theres settings somewhere.
