looking into a programer, what would be my best option for 03 4.6 gt

 

DIABLO or SCT. It seems many people have an opinion on these, but it mostly comes down to who is using it. I used a Diablo on my car after i had installed a few mods and had a nice jump in out put. Many people are switching over to SCT and getting nice gains as well. It all depends on what you got and what you know. I didnt have any one in the area to work on my car with the Diablo, but i had already purchased it, so i went to P and J's Speed Shop back home, and they did some nice work with it. Everyone in my area is using SCT unfortunately. See who uses what in your area. Unless you want to try doing it yourself!

 

sct for the win why because over then next day or so we will be offering a group buy on sct equipment to our members which will save you some serious money!!!!!! watch for the official GROUP SCT BUY coming tonight or first thing in the morning

 

That's the way to go!
