So I installed my CTS Thursday without issue. I have somewhere around 200 miles on it now running the canned 87 Tow tune. I just placed my order for my 87 Performance tune. I do realize that it is not even 0300 where I live, but I'm working nights. I provided all the information about elevations and what not in the order and I'll let the brighter minds that write the stuff sort it out for me. Thank you all for the input.
I've said it elsewhere on this forum, but of the forums I have been a member of, this place has more brains that understand the dynamics of making power the any other site I have been on. Please keep the information coming so I may become portionally knowledgeable about this as well...at least beyond the simple air in, plus fuel in, plus fire equals exhaust and a smile.
