I have a 281s saleen s/c with a smaller than stock pulley.I have a 03 cobra dual fuel pump an tank setup with 42lbs injectors an 90mm mass air.My car keeps running lean under boost and have burned the ends off of 2 plugs twice in the last 3 months.the same ones every time number 2 an 3 which are right under the throttle body area. I have the colder plugs awsfa12c in it gapped .035.Ihooked up my fuel pressure gauge an it runs at about 35-40 psi an under boost only goes too 55psi .Is that enough fuel an should i get a boost a pump like a t-rex or kenne belle too fix the problem.I have a 95 cobra with a vortech an under boost the gauge peggs to 100psi.
