I have already tried all of those suggestions. The line has been cleaned and still is as of the other day. Boost switch bypassed.

When I unplugged the ALDA, I plugged the boost line so as not to have a boost leak. On the test drive, I didn't notice much difference in off the line power but the top end performance was less than usual.

Scotch works well with a hot engine. At least when I burn my hand 10-12 times on the oil canister it won't hurt as much.
