my car kinda needs a tune now since i got the P+P intake manifold on there...

after running, it idles lean for ~3 - 5 seconds before it finally goes back to stoich. Also, when i first pull off, at around 1 - 2k RPMs it lags like crazynow.
Its also a little bit choppy/jerky in the rpms between 2500 and 3500.

i dont really have any real way to tune, b/c i dont have an AFC or anything like that. what do i do?
