Thanks for the advice! I contacted and e-tuner (Dux10) since he lives about 30minutes away from me in GA. endrswrd - I did not see a XPT map on their website for the AEM intake?? I did write to them 4 days ago and have not heard back. They don't have a phone number listed on their site so I am assuming you have to email and wait. I talked to Steve (Dux10) tonight and I think I will go with him. Based upon my conversation with him and the reviews I have read on NASIOC, he definately knows what he is doing!
