PCM Diagnostics & Tuning - What do ya think?

I have read the sticky and searched quite a bit but still have a few questions.

Would you guys recommend getting a programmer? I know someone that would sell me a brand new Diablo sport programmer for cheap bc he doesnt have the car anymore. I know getting a dynotune is the best way to go but its also the most expensive and i have a couple other projects going on now too. I am done with performance mods for now, so that may help get some answers too. Thanks for the help.

if he doesn't have the car anymore, hopefully he restored his original/factory tune to that car first, otherwise the predator is locked and you can't use it on yours.

he would have had to send the predator back to have the VIN unlocked so that you could use it for your car as well. Otherwise you will be only able to clear codes and monitor sensors with the Real Time feature.

sorry i didnt make that clear that i know that already. thanks though
