Should I retune after installing 4.08s ?

I've read the SRM goes out only if you track the car over 120+ mph with the 4.08s. Then you have to shut it down wait for a few minutes and turn it back on and it's working again. Also read its only going to be off by 2 or 300 rpms when it does work.

Cruise control I've read is hit or miss whether it will work with the 4.08s or not. Z is not a DD so no biggie either way.

Edit: CC works with 4.08s IF you have a manual. AT with 4.08 needs a tune to get the CC to work.

This is what I've read from various sources within the Z/G community forums across the net. Everything I'm reading could be dead wrong of course but this is what I'm seeing from people who've done this to the Z's/G's with the VHR and AT or MT.
