The early TST 03 twins program was all in at 12 psi boost, the later programs including the current 03 twins was/is less aggressive than the original. There were a few folks (Tomeygun for one), who claimed Mark Chapple built them an 03 twins program that was not boost dependant, and was able to full fuel right off idle. Not sure I believed this, kind of like the folks who claimed to have special/unique TNTR Smarty software...I have a TNTR program with my first and last name right in the software description, comes right up on screen, S04_Revo_TNTR57_Jess_Page, It is vinlocked to my truck, but it is no different than anyone else's TNTR57 version.
I still have my TST R37 connected to my truck, it is turned off (0/0), setting in my ashtray, also have a bypass plug should it fail again...lost my train of thought...where was I going with this?
