I have had this Trinity for a couple months now and only used it for data logging and to clear Trouble Codes on my 08 Mustang GT. Today I got the nerve to try to install a 93 Octane tune in it, and all I have to say is Holy #$%#! I have an Automatic and I took off from a dead stop and the car snapped my neck back. I was not prepared for this unit to affect my car THAT much! Diablosport knows EXACTLY what they are doing. I can barely believe that just reprogramming the PCM can affect the car that much! It's like I am driving a diffrent car now...
I would recommend an Airaid Intake or JLT or the FRPP/Steeda 90mm (metal box) intake. Those three make the best performance increases and have DiabloSport tunes already loaded in your trinity for them.
This unit keeps surprising the hell out of me... I don't even have to pay someone for a tune for this mod?! Life is good... I am glad I bought this unit and not that 1200.00 SCT piece of crap...
