you may not need any tuning; you won't know until your new MAF is on and you use ATAP to look at what's going on.

When I installed my headers and y-pipe, I was running WAY to rich, smoked bad at WOT. I added a lid and MAF ends w/ the MAFT to try to lean it back out. Luckly I found a local guy that had the ls1 edit program and he tuned it with the MAFT.

Kinda not an answer to ur question, but gives u an idea. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
