Should this be connected to the intake before or after the throttle on an S4 TII? At WOT it wont matter, but for cruising at part throttle, wouldnt connecting it pre-throttle inject a little more oil (good for lubrication, or too much)? I had it hooked up to the vac nipples on the UIM, but they didnt seem to be getting much vacuum at idle (the little vac nipples sticking out of the UIM, though physically post-throttle, are connected thru the rubber spacer and a tube to the air flow pre-throttle), so i moved it to the nipple on the LIM right between the primary injectors. Which do you think is the better location?
