HIGH IDLE, ERIC CAN YOU HELP

[1buick]

The car idles at 1200 rpms. I checked for vacum leaks but i can't find any. I also get knock retard at 15lbs of boost. I have a progressive alcohol system and running a TT chip. I first noticed this after a pass down the 1/4 mile. Could the timing in the chip have been thrown off. I acts like the timing is to high. My speedometer isn't working so i can not adjust my timing in the chip. Eric can you help?

If the high idle happened after a pass, start looking for a hose that blew off.
For knock at 15psi, make sure alky is working, check fuel pressure under boost, make sure MAF is hitting 255 at full boost.
What were your O2's?
