Recommendation for remaps?

[urfy]

Hello all,

I have now completed my 2.7 build and in the process running the engine in, i am running the standard Motronic 1.3 management system do i really need a 2.7 chip? The car seems running to be ok but was wondering if i have to put a 2.7 chip ir is it to run it with the standard chip?

Also I will need a remap once it has run in, I have tried but failed to find someone who will do the remap with the standard Motronic 1.3 system, can someone recommend me who can carry out the remap?

Many thanks.
