Hi guys, once my forged engine is built im wondering what to do to run in. It currently has an emanage blue mapped on a tf035 at 1.1 bar. I have a td04 and 420cc injectors whoch i want to get the car mapped on when it goes for mapping again My question is, if i keep the standard injectors and TF035 (which the current ecu is mapped to when it had standard engine) would it be ok to turn the boost down for the running in period? Then once its had a few 100 miles on it, fit the td04 and 420cc injectors and take for mapping is. My worry is that the current map wont match the new set up exactly but would it fuel fine at lower boost? Thanks guys, dan
