the TVSV gives you aoption to have higher boost in 3rd+ gears. when you disable TVS, you dont have it. so it will not be above 0.5bar without a boost controller. that is what you need if you want to raise boost pressure. do at your own risk of course.
Seems easy to do but what if you dont have the t-vis and turbo VSV's or the vacuum tanks. i got my 2nd gen jdm spec 3sgte a while back to do my swap. i noticed were the accurator goes is missing and blocked of with two screws. the harness also had the t-vis and turbo VSV's unpinned, im guessing due to no vsv's being present. so my question is how do i delete my T-VIS or has it been taken care of and all i would have to do is block of the hose from the wastegauge?
