Hey guys i just bought a civic with a built d16 turbo engine with the common vitara setup, its been running fine but the manifold was cracked badly and blowed like hell also looked like a 10year old welded the manifold so the quality is s*it. im not a bad welder and considering making a new manifold myself, but the flow will look a bit different, my question is does the ECU needs reprogramming with a different manifold?
Thanks in advance
