I know i should get a tune after each of the following but is it manditory? I want to put on my Mac mids, then go to the track, see what they pick up. Then change heads for the home poeted see what they pick up. Then the cc503, i already know not to run that without a tune, but what about the other to? Thanks

Headers: no tune required

Ported heads: yes

If your car is indeed a 93 I would probably tune for each. With a 94 I would trust the MAF to help compensate for things like the headers

Ion told me his baseline performance tune is calibrated for headers out of the box.

My car is indeed a 93, and i use pcmforless on the tune. I was hoping to avoid the 50.00 dollars a reflash for each one and maybe get some solid numbers for each upgrade. I am going to also make some runs going from the K&N fipk to the ls1 lid conversion, i will bet some people would like to see some results for all of these upgraded runs. Right?
