Astra VXR reflashing software

Hi guys, I've looked about and it seems very expensive to remap or get the tools to remap the factory ecu myself, over 2/3k£.

Am I missing something here? Is there a way to get into the ecu through the obd port and change maps without having to drop 3k into tools!

A standalone piggy back install for about 1k is looking more tempting at the mo.

Thanks James

See if HP Tuners supports it.
