never turn the PC off - its easier that way
Im no expert on powerchips for Renaults - the likes of hillpower, superchips & Unichips are more recognised as far as I know.
Although there was a small debate about hillpower chips after a Rolling Road session on renaultsports forums. I cannot remember what the problem was.
I spoke to superchips about my Williams as they did my Fiesta RST and the basically said you could see UP to 10bhp but its all car dependant. Also you could end up with the same Bhp as you started but maybe more drivable.
If you going for big power mods then Unichips are the one as they as mappable and can be re-mapped for different mods and states of tune.
Hope thats all correct - were missing BenR here but im sure hell appear.
