Alright Well Were At The Track (The Car Is) And It Still Is Dying When We Lean Off The Throttle. Replaced The DME Relay + New MSD Coil. And Still It's Pulling This Spuddering After A Good Lap Session. Like I Said It's Not A Problem During WOT It's After A Good Beating On The Track, And It's Popping Meaning I Know There Is Fuel, It's The Detionation That Seems To Be An Issue, One Guy Is COnvinced It's A Ground Issue. Would Love The Input, Any Ideas Or Things To Look For. This Is Only Day One Of Four!

Well, if you are having detonation, then you sure as heck don't have enough fuel! Check your fuel pressure regulator.

What Am I Checkin' For.. I Am At The Track??????

You need to start by checking your fuel pressure. Normal reading at idle is about 2 bar, 1 bar after 20 minute leakdown, and 2.5 bar with the fuel pump relay jumpered on the 8V engines.
