I converted my 91 Daytona (previously 2.5 T1/auto) to 2.2/5 spd. I'm using a VNT computer and simply using one of the solenoids for the wastegate and added the charge air temp sensor. The car starts just fine, boosts too. But the CEL is on constant and feels like it's in limp mode. Very lethargic through out all RPM's. Checked and double checked timing of everything. I check codes and get 12, I kid you not 64, and 55. Now, before you post that there is no code 64, there MUST be. The SBEC is throwing it, it must mean something. I know how to count the flashing light So, guru's of TD's what do you think?
