I had my car mapped last week, custom code phase 2 on k03s and all bolt ons, then i fitted a boost gauge and boost was low about 16psi max, this morning unplugged the maf and it was a lot faster and boosted up to 20 psi. My question is because it was mapped with the faulty maf if i fit a neew one and it boosts higher will it need to be adjusted for fueling again because i dont want it to run lean.
