Wow! Something is very wrong, you are dangerously LEAN!
What exactly does the AFR graph look like?
What RPM are you hitting that 17.5:1? Through the full range or at redline?
Is it possible the wideband is faulty or wasn't hooked up correctly.
What is your boost spiking to? You should be seeing 10:1-12.5:1 depending on certain variables.
