Why would you waste your time buying a base map from a different tuner? If you're taking it to Tony you may aswell let him supply and tweek one of his own well established maps.
One if you read above i already said one of tonys or say msds base maps for example..
Two,who said he was deffo going to tonys??
At the end of the day anyone who can use a spanner can do the said conversion above and any one who can map out there with webber software can download a t34 55lb base map and go from there..
