During testing, I could not get the engine to run well at all if the MAP lines were only connected to just one of the TWM ports.  Now that I look back and add it all up, I think the jet/filter idea is the way to go.  Probably just the filter would be enough and easier to install.  Who tossed in that idea, was it Bulent?

It was not me. I’m reading all this and concerned that after all the work I’ll have to struggle with the same problems?
