[s-cars] Bucking at high boost levels- POS?

[chris chambers]

Bob,

This sounds exactly like the problem I had. You have either a bad MAF
(a new MAF is mucho $$$) or a dirty connection on your MAF. 

Get yourself a can of electrical contact cleaner and try cleaning the
contacts on your MAF and the cable that connects to the MAF.

Good luck

Chris
