Yeah, I agree the SAI system is a large expense for a very small benefit.

I think I'll explore option 1 though.

Thanks a bunch for your trouble. That's very useful information. And I will look at manifold vacuum and check for cracks in the line to the SAP valve. Likely to be Friday or Saturday.

As you...

Also what should the stroke on the...
