I have an 89 5.0 LX. I have swapped out my AOD to a t-5. I have Mac headers, Off road X pipe, Mufflers and tail pipes. I have a March Ram Air Kit and a hyper tech chip and fuel pressure regulator. I have by passed my smog pump. Every thing else is stock including the fuel pump. My understanding is stock 302 runs better lean.

What should I set my fuel pressure at on WOT. I believe that you set WOT when you take the hose off the fuel pressure regulator and plug it with your thumb.

What should I set the timing to with these small modifications.
