Need Help on '04 5.4 custom tunes.

[Tonto87]

Late last night I was reading thru the vast amount of info on this site.
I saw a thread about '04 5.4s having trouble running lean with CAI and advise to someone to run (back down to his 87 to and perf. tunes. I can't find that thread again this A.M.
I just ordered a Gryphon CS and ordered 89 tow and perf + a 93 perf. Based on info that I could go one step either way (run 87 on the 89 and 91 on 93). I had my HEX included with order.

Should I try to contact PHP and revise my order?
