2.2 C5 tuning box

Post by Peter.N. »

I fitted the box to the C5 yesterday, no problem fitting it except that you have to remove the fuel filter to get to the plug and even then its tight but didn't take many minutes. Went to Axminster this morning, no apparant improvement in fuel consumption but it goes like a rocket, so there will probably be a tuning box for sale.

From the computer. Thier reason for it giving a better consumtion is that you can use a higher gear because of the extra power but as I rarely exceed 2000 rpm in any gear and mostly use lower revs than that I can't see how it will help. It only averaged about 35 mpg this morning, admittedly that was with a lot of stop start driving, I have yet to try it on a longer journey but it only managed 45 mpg on our trip to Kent at the weekend. If that's the best it can do it will be for sale.
