Check to make sure your getting fuel, spark, and compression to each cylinder.

Will try to idle without the filter to better find some vacuums.
Also will try with burrowed coils.

PROBLEM SOLVED

Skunk2 Racing TB has a carved channel on the back that vacuum feed the MAP.
The stock OEM TB gasket DOESN'T cover fully the carved channel. There fore the vauum leaks.

With Vacuum leaking MAP read -0.03.

We filled the channel with silicon.
Deleted with a metal strip the map location (on S2 the map is facing the alternator)
Relocated the map and T'd on a IM vac line.

MAP was reading correctly, car tune was adjusted.
