Car dies when load hits when first put in gear and can't figure out the fix....
Basically, if I set the tb set screw to make everything ideal with the iac steps at idle, it will idle awesome in park/neutral, but as soon as I put it in gear, it dies, but if I give a quick blip of the throttle as I put it in gear, it will be fine and idle fine. As soon as the load hits when it goes into gear, the iac steps jump up, but it's not enough or not quick enough to keep it goin. Now here's the problem, how the hell do I fix this, cuz the computer does not know when the car is going in gear to compensate with extra air since i'm running a turbo 400 in the car. If I open up the throttle blade to where it doesn't die when put in gear, it starts surging really badly in park/neutral when the load is gone cuz it has too much air and the iac counts are at zero, so it can't close anymore to stop some airflow to kill the surging. Also (i'm assuming b/c of the big cam) I have very little vacuum at idle (the map kpa is really high, between 75 and 80), and have no vacuum leaks, and i'm sure the shitty vacuum isn't helping the situation either.
So are there any guys on here that have a t400 or glide in the car with a radical setup that got it working, cuz it wasn't so bad with the stock intake (would surge in park/neutral, but only like up 100 rpm, then back down and so on, so it wasn't really noticeable), but as soon as I put the 90mm on, it made a little problem a really big and annoying problem (now it idles up to 1200 and swings up to like 2000, back down to 1200, back up, and so on)!!! Thanks for any help guys, cuz i've been fighting this for a while and it's really starting to get on my nerves!!!
PS - Right now the car is SD mode while i'm dialing in my ve table, and then i'll be throwing the maf back on and dialing it in.

You can also raise your idle to sort you out.
Also sounds like you need to do your RAF table.
