Hi guys, looking for some advice... Here's a little background to the problem! Basically I bought the car over a year ago and was quite happy with it, wasn't the fastest thing in the world but it was ideal for what I needed. Then I got the urge to have the car mapped but wasn't convinced there was much difference! So after a bit of swatting up on here I decided to replace the Diverter valve with a standard revised replacement bought from awesome, after fitting the valve myself I couldn't believe the difference, easily the best £50 I've spent on a car! This has been fine for a couple of months but after being away working for a couple of weeks I jumped in the car and it seems once again to be a bit "flat" through the revs, so I suppose my question is could the Diverter valve diaphragm have split again after only maybe 2000 miles max?? I know the easiest way to find out is to take off the Diverter and have a look but I'm not going to get that opportunity for a while! Thanks in advance for your help!
