Mods

trick flow top end
30lb fms injectors
70mm tb and egr 75mm pmas set up for my injectors
bbk fpr
190 pump walbaro
18 degrees timing

On part throttle The cars seems to pull harder than at full throttle

I can feel the car fall on its face alittle when I hammer it and the exhaust note gets smoother and quietier ?

Reason I ask is that black smoke billowing from the tailpipes is usually indicative of an overly rich condition. Did you plug your spout connector back in when you last timed the car?

Other than the feeling the car falls on it's face at WOT, does the car run okay, just driving around say? Any dyno tuners in your area? May be worth a trip to get it lined out. Coud be running lean at WOT as well. Have you played with the fuel pressure any to see if it wants more or less fuel?

Yeah, it could be lean enough to rob power, yet not so much it detonates.
