Hey guys, I've go an SCT SF3 that my stepdad an I had from our mustang. I've got to get it unlocked but does anyone have a preference on who to get a custom tune from? I'd like to use the SCT tuner but if anyone has a company in mind that will get me good numbers out of my 5.4 I'd greatly appreciate it. Mine seems to struggle with the 33s I have on it and I eventually want to go with 35s so any advice would be appreciated. Also I have a rearend with a code of B6, I believe that's 3.73 gears so would anybody suggest steeper gears? Such as 4.11s? Thanks

 

By the way I have true duals an a k&n CAI

 

Troyer performance does really good with custom tunes

 

I just got 5 custom tunes from mike buyler at 5 star tuning. He has a great reputation and hes is very quick to respond to you. Very good customer sevice. I have an 05 fx4 . When i put the performane tune on i was amazed with the response my truck now has. I highly recommed 5 star tuning

Not sure if the Edge CTS is what you are looking for, but I just got that and am very happy with the results

 

Thanks guys. I'm going to get in touch with him. What gains did u see Rbianca?

 

I havent had it on a dyno so i couldnt say. But its a major improvement from stock. Search through the forums and somone could prob give you a better answer.

 

Thanks bud
