Where in Wales are you??
Lots of Corsa VXR's around South Wales; they're fun to wind up
Down south in Newport. I see a fair few vxr's here and there. I'll wind up the next one I come across and see what happens
You definitely notice the box more when you take it off. You quickly get used to the extra power when you stick it on. Let us all know your results with the "signpost" test or similar.
Ok I feel like a bit of a k**b now... Put the car back to normal on saturday and I definitely noticed the decrease in power. Low down its similar (though still noticeable compared to box) but high end there is a big difference. Anyone know of a dyno near this area? (south wales) Im curious to know what this car is pushing in stock compared to dtuk box fitted.
Im also trying to fiddle around to see which map gives best mpg, i tried a 200 mile journey going at 70mph with map 3 minus 3 and i got 49mpg (mfd stated 64mpg) which is basically the same as i what got on a 120 mile journey using 3 + 2. Any one else played around with the maps to get good mpg?
