Well the cars been running a bit rough ever since the engine swap. Ive got the idle set to about 1000 rpm and it still drops and surges back and forth. As of now the timing is at 12°. Ive read on some threads that once they tuned the car, alot of idling and drivabilty issues were resolved
Your statement is not untrue. It is however, only small portion of the whole truth. What I mean is:
You do not appear to have any mods that require digital tuning. An intake, throttle body, and cat-delete, are all within the EEC's ability to adjust.
More often than not, the surging and drivability issues that you are experiencing are the result of an improperly plumbed vacuum system or a flat-out leak.
I'm going to post a link to a checklist that jrichker put together with his data and the input of some others. When you first look at it, it seems very daunting. It's really not.
Just break it down into individual tasks and do them one at a time. If you get stuck on something, post your question about that specific thing and either myself,
@jrichker (if he's available), or another SN member can help you throug the rough spots.
You're probably thinking right now, that this is a waste of time because you read on the internet "this" or your buddy who is a mechanic said, "that" and now you want a tune to fix the issues. My suggestion is that no matter what tune you put on it, it will still be broke until the underlying problem is fixed. Your issue... Is in this checklist.
"How do you know this"?, you ask.
The short answer is, "Doritos".
First: Pull codes and post them ALL here, even if you think they are not related

We will address the codes before moving on.
Next: Run the surging idle checklist from top to bottom

Read through this so you know what to expect.
