Standard chip has to be removed anyway to fit a programable one.
Mine has all the "standard mods" and only makes 154bhp so not everyone can get 160bhp.
Plus its subjective anyway as Rolling Roads differ and as yet nobody except Khare has stated which RR gave those figures.
As a Forum we know that JKM and Rtech and Carbon Chiptuning all give similar figures.
So those that say they get 160bhp with just an ebay chip I take with a pinch of salt.
