[urq] stumble at high boost/full throttle

[Brandon Rogers]

Have you relayed the fuel pump?  That (red?) wire gets old and brittle with
so much voltage - so check voltage to the pump.  Lots have reported better
top end with pump getting full voltage.

Hey all-
 
 Car is running great, but.....
 
At full throttle over 14 psi, car stumbles and my A/F gauge goes to lean.
 
 Checked throttle switches...both good.
 
 Check CPR hoses....all good.
 
 No vacuum leaks.
 
 If I back off just a bit, I get stoich/rich.
 
I've read it could be ignition related. Plugs are new (maybe 2500 miles).
 
I checked the wires....I have two that read " 0", two that read " 5.xx" and
one that reads "11.xx" 
 
Idle is great and highway driving is great, just this high rpm boost issue.
