For one, RGM charges an arm and a leg:RedNo:
Secondly it must be the Uniq with the module to have up to 5 different maps to interchange between.
IIRC, ROSS charges about R6k for that.
IMO, ON a turbo car I would go for software as there are proven gains worth every rand.
WRT to the Unichip, i dont see splicing the harness as a major issue. U also don't gain much with just a Unichip. It's purpose is to bring Mods into harmony and function efficiently together thus gaining the best results from the mods. That is where the gains will be.
If i use my car as an example, a stock 330i pushes between 113-117wkw at the reef, depending on its condition. Mine pushed 121kw on the before run on the dyno, this was after the decat and full exhaust. So there were gains. Then the UniQ was installed, mapped and tuned and the power jumped to 132wkw. This coupled with a short ratio really made a different on the blacktop. So there is merit in saying that the Uniq refines mods and extracts the best gains.
