so, my buddy has a '94 LS teg with a B18C1, stock internals, and this stuff installed/operating currently:
-T4 turbo
-P28 ECU (chipped, presumably)
-VAFC (dyno tuned)
-missing link

and the car started doing some weird hesitation-under-30%-or-more throttle thing, and we traced it back to the missing link.

so, being the typical broke college student he is, he wants to find another missing link, throw it on, and call it a day.

i am trying to convince him to get the system done right, and im thinking that the best idea is a 3-bar MAP sensor, with a crome tuned chip for the P28...
so he would be looking at $100 ish for the MAP sensor plus tuning, which varies...

so, what i want to know is, are there any options im leaving out?

thanks in advance for any ideas/opinions/suggestions.
