it pull wonderful thru 1st gear hits roughly 1.0 bar, no problems when I shift to second it pull hard until about 4500rpm and .07 bar and hits fuel cut. im stumped as to why its hitting at such low pressure. i have an ls400 afm for it but no injectors. opinions on what i should do next? :1zhelp:

get a rebic lc they are great for tuning on stock injectors they really do work

drill out the stock screw on the afm and see if that helps

i took a look at that and i couldn't figure this out. Do you actually have to drill to get to that screw, or should you be able to just turn it? I know the screw is on the bottom of the afm for the idle adjust or something but i couldnt figure how to get to the head to adjust it..

You actually have to drill to get to the screw.

Toyota initially sets these, then plugs the hole so we can't muck with them. Drill out the cap in the hole and you're good to go. You should be able to see where the cap is installed if you look on the bottom.

My advice is to pickup a set of 550 injectors and install those.
