Spend a few minutes of your time searching for "305 TBi to 350 TBI" or alone those lines. The posts that come up will tell you everything you need for this swap. Because I am so confident that you will find your answer I will shut this one down to save some bandwidth. You can use the stock computer but you cannot use the stock chip.
