    @pacecarta i ran the car this past weekend, i set the fuel pressure at 43psi with line off , under boost it went to 68psi, my mv reading in 3rd gear was 832 with 0 degrees of retard, but the car just felt like its not pulling all the way through the quarter, the next pass i turned the fuel pressure down and my mv in 3rd gear was 790 with no retard, but the car still felt like it wasnt pulling through the 1/4 mile :(

    what chip ?

    dont use fuel pressure to lean the car out
    when was the last time the module coil pack was tested
    what plugs what gap
    id run acr42ts on race fuel at your boost and tighten them up to .028

    whats the fuel pressure through the traps ?
    what was the mph 1/8 and 1/4 running with 790mv

    the plugs are ac delco r42ts gapped at 30, the chip is a turbo tweak set up for 110 races gas, the fuel pressure through the traps on the 790mv was 60psi, 1/8mile mph was 85.84mph 1/4 mile mph 105.26
