hey guys i was just wondering which is better to start with the dhp pcm or the reprogrammer. i have an 04 ls and i saw these two next to each other on the zzp website and was wondering which one to start with. are they the same thing or not?wats with the "race cal, adjustable timing" options you have to choose from. i was told to wait till i reprogrammed the car to install the 180* thermostat so that the sensors and crap dont mess up . anyways what kind of gain will i get with the pcm, im thinking of getting this one cuz it seems easier to install, then the thermostat, then the reprogrammer (if there is a difference) whatever can someone please help me?

 

I HAVE A HYPERTECH THAT WORKS PERFECT FOR WHAT I WANTED, WON'T LET
