Hmmm seems I've been misinformed, always been under the impression that the silver tops were 170bhp & the black tops 180bhp, oh well. Loving the 190 conversion but the lack of ITB's puts me off a bit lol! I'll certainly keep an eye on that I must admit 838kg is a bit of a disappointment though, thought more could be taken out, but I am basing that on what I know about the clios, a mate has got his down from the std 1000kg to 790kh with him and some fuel in it. I've had a look at taggys as suggested & think EP82 is probably the better option for this build but we'll just have to wait &
