ISO a good working TPS. PLease

Any tips on tuning spark\ignition advance to improve off boost response or to reduce turbo lag with a big turbo?

hello guys!   my brother and i are thinking of upgrading our intakes on my 88 and his 87. I remember reading something about being able to use a Hyundai intake manifold because it is a direct swap. So i have a few questions...   1) what year and what kind of hyundai is this from? 2) Is it really a direct swap? 3) if its not what upgrades or what do i need to manufacture to make it fit? 4) Will i have to do anything to my ECU? 5) anything else i need to upgrade or change in order for it to work?
