Boosted Performance round 2 list

Mitco39

It was leaning out because of the supply system our cars have. At the time I was still running the stock wiring to the fuel pump, but I have since ran my own 16 gauge ( I believe) wiring right to the fuel pump which has helped.

I personally believe that inadequate fueling is responsible for most of the boosted engine failures, it only takes one quick drop in fuel pressure to lean out an engine enough to go boom.

Right now my car is staying at 10lbs until the fueling system gets upgraded, I am very interested in what FI has coming down the pipes. Everyone said it was fine but seeing your fuel pressure drop 10PSI at wot, then creep down to 14PSi at the higher rpms was a bit unsettling. Not only does this make your fueling system struggle to keep up, your now spraying your injectors much longer to just get that same amount of fuel in which just has to be creating a inefficient burn.
