Thanks david!!! My cold idle problem is no more!

Custom tune is a must, I highly recommend it to anyone that has modded their mustang! I plan on getting a Burn1 and hope to get a data logger so I can tune this myself vs having David tune it (that's a lot of phone calls and mailing things back and forth). I've really learned a lot from this whole thing. I also plan on posting some info on here for others to learn.
Again, Thank you David for helping me out so much, you really did go above your word every time! It's nice to know people like you are still around.
btw, I believe the cold idle problem was due to MAF curve and injector timing.
