The reason why was due to the cost of the map required which is over £600 for T2 compared to £100 for weber. + once he sells the T2 and loom it will pay for the cossie ecu and map all in one.
All the parts required for running on T2 is the same for weber so no extra costs at all.
I had the same setup for my first car which was done the same way. I bought a loom and ECU off ahmed for loads of money then was told that the cost of mapping was as much as the ecu. What was the point in that.
In the long run will cost less to have the same result and can be done much easier.
You had a touch with the cost of the T2 setup so if you sold it on and fitted weber you will save money. Fit the T2 and get it mapped in the end will cost you more.
Simple as that.
