Custom tunes / headers

[jconna]

Well it looks like my Gryphon will be delivered tomorrow and I'm really looking forward to it. As part of my order, I purchased the 87 perf and 87 custom tow and understand that will be a 6 -8 week wait which is perfectly acceptable....No major rush. However.....I provided information per my order regarding a complete dynatec header system I currently have setting in my basement and have a question on that. I know I'm weeks out on my tunes but don't know for sure if I will or will not have my header system installed before I receive them. If not.....Any opinions on whether I should wait to load those tunes until I actually get the system installed? Do I have any legitimate reasons for concern?

When you get the email or pm that your tunes are done and then you load them on the gryphon. Then you put the headers on then load your tune.
Make sure you have an extra set of NEW front O2 sensors on hand.
Also make sure everything is tight with NO leaks, especially at the header flanges.

Thats along the same lines as I was thinking.....Waiting to load the custom tunes until after I get the headers on. Can I ask the significance of the NEW O2 sensors though? Thanks

just incase the old ones do not want to come out or if they look bad replace for better readings.
