I was told it was standard and only bought it as it was very cheap but running poor, this was down to the air box not been tightened at either end and the recirculating valve not been tightened up. After this it was fine bar the 4th gear issue.
was going to ask if i could find a way of knowing if it has been mapped and if it may have had a dump valve or other minor mods took off?? N could be running slightly off.
Many thanks for the reply though
