Thanks-thesatinpumpkin. decided to forgo the mani and get shorty headers. DiabloSport InTune just came in the mail and I installed it yesterday. Ran the 91 octane tune for a bit and then tried the diablosport tune (I think it is the 93 tune equivalent) which is what I currently am running. I have not noticed a huge difference, but I havent really stomped on the truck yet. Are there any ramifications to installing the tune that I should be concerened about?
Headers are going on this weekend...hopefully they fit right to the stock exhaust.
