Hi, I am quite seriously disabled and so I have a Motability car - a DS3 DSport as it happens.I only paid for the extras I wanted like the larger rims, a full-size spare (who needs shopping space ;). My wife, who actually drives the car and loves it but last year I noted many chipping companies offering variouls solutions to increase power and torque (the latter more importantly as my wife's one failing as a driver is that she never changes down before encountering a roundabout or T-junction. The car struggles off the line in 3rd but it's NOT safe if she's trying to keep the blower spinning ready to go. Now, I noted that with the updated model lineup has a a number of 'trim levels' that all come from the same engine as the DS3splort+ (115 BHT) and the self-same engine with a different chip powering the 135BHP. Does anyone else wonder,as I do, if the DS4 style (135BHP) ICU can simply popped into place. I'm just happier knowing Citroen had done the work and would overcome the slightly show take-offs due to the 18-inch rims we have. Anyone else considered this as a route to increase performance?
