Quick Question; Haltech ECU

[rocksteady_racer]

When you install the haltech ecu the map sensor replaces the maf sensor right? or do you need a maf too? And the other question do they sell aftermarket intake manifolds with map sensor adaptors built in or do I have to drill like a greddy manifold or something. Ok thanks in advance.

No more maf.

No the greddy intake manifold (if its a real one) should have a hole pre-tapped under the center of the plenum. Get a pipe fitting nipple screw it in (doestn have to seat all the way just make sure it tight) and run a short line from that nipple to the map sensor. I mount the ones i install on cars next to the shock towere or near the fuse box etc.
