It is most definitely a typo error as there is no way with just
a 'remap' or 'chiptune' that you can possibly get 295bhp...FACT.
I'm thinking whoever 'keyed/typed' the figure in suffered from
'fat finger' syndrome...and hit 9 instead of 0... in other words 205bhp.
Now that figure IS attainable via a 'simple' remap with no other mods.
