Hi everyone

I am new to the forum and would like to extend a huge thank you to the guys that have added to the content on this forum - the information and help offered to is commendable.

I am very new to tuning and have a 2008 Opel/Vauxhall astra H OPC/VXR.  My vehicle has been heavily modified (bigger FMIC, Injectors, Turbo, forged bottom end).  I have decided to learn how to tune my own car due to a number of mechanics and tuners locally being dishonest and stealing my money or breaking the car to purposefully bill for repairs. 
I hope to learn from this forum and I am happy that I stumbled across it.
