i need to know if anyone has done this in their 91-94 k.
if you have can u please tell me if you needed to tune it, or not. and if you do, then what did you do?
please post your setups and results.
i'm hoping that all i have to do is retard the timing, since all i burn is 93 (we have 87-93 in va) anyway, and the stock map seems a lil rich.
also, i had a look @ the stock manifold. now the holes seem plenty big, but the bends are kinda lame.
so if anyone has tried testing the difference between the stock manifold and an average ebay 100-200$ header and knows the results and if it is worth it to make the switch please let me know.
i've tried searching, and many discussions appear but one with the direct answers i'm looking for. so hopefully this post will yield some answers and hopefully no debates. thanx
