Hello Rammie,
I had the X power upgrade fitted to my CDT a couple of weeks ago at Primrose garage in Clitheroe, Lancs. It cost £200 and was worth every penny. Fuel consumption is just the same as it was before and you can definitely feel the extra grunt.

Regards, Stelad

You will be able to get it from any X-Part dealer for £199 - that is the new price.

You'd then have to get them to install it - you need a T4

As you would have seen from my previous post the nearest one to me quoted £400 - £500!!! Then considered it not worth doing!
Thanks for all the messages, I am considering using Simon Coe who fits the Upsolute system and appears a genuine guy and will fit it at my home.

Hi Rammie,

I already have a 131 ZT and want a futher upgrade. I've pretty well decided on a Ron synergy box. But my insurance co wont let me do this, as they shy away from anything that affects bhp. (Ive tried sweet talking them). But I will be doing it when October comes.

You havent said yet if youve looked into Roveron Tuning. I'm sure there are alternatives, as you mention, but I wouldnt make a decision until youve looked at what Ron does. He certainly has a lot of happy cusotmers on this site.
