If you have thought it over and chosen to "Mod" it first off KEEP EVERY STOCK PART YOU RRMOVE !
Cold air intake is generally the first mod people go with. I did most of my engine all at once. I really wanted to feel the difference from stock to WOW all at one time.
You will hear companys' names such as "NeedsWings", TVT more than anyother but take everyones' opinions and learn from them. Many sound as though there getting kick backs from these companies.
Asking on this forum can get you more info than you will ever believe.
Good luck with the SRT...
