Ahab Needs Help

[kerry griffith <kerry.griffith@m.k12.ut.us>]

I'm hoping for a little more direction before the Great 
White Whale goes to my mechanic this week.. 
	Symptom: When car(91 200q) nears full boost, power 
suddenly drops off substantially and the motor runs quite 
roughly. Boost also drops. If I back off on the gas, all is 
well again.
	Plugs have been replaced, IC to TB hose replaced, bypass 
valve is recent, hoses have been inspected closely (yup, I 
know I still need to pressure test). 
	Suggestions include: frequency valve, plug wires, 
cap/rotor, static timing, pull fault codes. 
	If anyone has any more helpful ideas, I'm all ears.
Thanks to those who have contributed thus far.

91 200q (not all is well)
89 80q (always runs perfectly)
