I'm running 2.9 pulley, 42# injectors, Bad Mab header, Slp Loudmouth exhaust, Step colder plugs and injen intake. which do you think is better for my car. Has anyone used any? if so what are the results thanks

 

That depends on what you want and who you know.

With HP Tuners you will have a wide range of people to choose from for tuning... so do your research. Also you will need to either find someone with the cable or buy one yourself.

With Trifecta (I’m tuned threw Trifecta) Only one guy does all the tuning, his name is Vince. but he has lots of local guys who own the cable and will help you data log and be the mediator for your tune. His tunes tend to conservative... so you will never have to worry about running too lean of a tune.

Either way is good, just know that when you start data logging with Vince (trifecta) if your running too hot or don't have supporting mods for what your running he will not dial in your tune until you get it fixed.
