    External IC ? Maybe ?

    I am trying to figure out my next round of mods here for my 2006 RXP and I am starting to lean toward an external IC. Yesterday I ran 76 (@8060 touching 8100 and bouncing down a few times) with the mods below. With that being said based on my mods / speed do you think I would be OK fuel wise? I have read some conflicting stories on what injectors are needed at different levels. For the guys running a AF gauges what ratio are you shooting for? With my turbo on my car I shoot for low 11's on pump (93) and lean out a but high 11's low 12's on race (112)...Is this similar to what this camp is doing ?

    S3 Charger, Rear Intake, 15/21 Prop, Riva Intake grate, Thru Hull exhaust, Green 42# injectors.

    Thanks,
    Nick

    your timing map is holding you back
    you can not make good power stuck at 15-17* timing
    timing makes a big difference to what is a safe afr

    Assume that is pre defined via the ECU ?

    yes on the older siemens ecu does not like boost over 7-8 psi
    at 11 psi and over timing is 15*

    So would think a external IC would be the logical next choice ? or would that money be spend better else where ?
