I am wondering the same thing, unless it has an aftermarket adjustable fuel pressure reg.

What air fuel ratio was it runing at WOT? Generally lean running is caused by dirty/stuffed MAF sensor, bad injectors or fuel system, bad O2 sensors or intake leaks.

Do you run it on 98?

My EL V8 pings on anything less than 98 Octane.

How old are your 02 sensers???
I would say they have cleaned maf and checked that its functionable???
The tps voltage pressivley goes up as throttle opens???

get an MAF from a Mustang or EL GT, they are bigger and more easily tuned.

My mate did this and worked a treat.
