Programmer AND PCM tune?
 

So, I've read a lot about blackbear performance and Hypertech scanners...

But my question is.. can you use both together?

And if you get a PCM tune and then say... upgrade your gears and go to bigger tires.. how do you compensate for that with just the blackbear? Would you have to pay 240 again and get it completely retuned?

The reason I ask if you can use both is because my speedo is off already, and I plan on upgrading to bigger tires and gears.
I wanted to get the PCM for performance, but the programmer for the speedo (mostly). Just weighing out options.
