Hello I have GS300 2000, and i want to make it manual transmision, but a few people told me the VVTI will not work if i remove the automatic tranny...is that true? How can i trick the ECU if i put the manual tranny.? Also i want to know if exist some performance chip can remove the rev. limiter or ECU upgrade... Thanks a lot for your advices, Franco
