What tools can be used to flash a 2004 Volvo V70 2.5T? Also, what would be the most convenient settings for this engine, it has B5254T2 engine with automatic gearbox, front wheel drive, 209 bhp/330 Nm original. It has 188k kilometres on it, and as it's a 2.5T with low pressure turbo, one can't get much more out of it than 240 bhp/385 Nm, or so I've read. Otherwise the gearbox would fail, or bent rods etc. which I do not want. The commercial softwares are a bit expensive, so I thought why not learn everything myself.
How much will the hardware/software cost? What hardware would be most capable of modifying more than just this car (other make/model), as this car most likely won't be my last one. :)
