    I have just purchased a Motec for my MPI supercharged Apex! Martin at Precision Sports will be doing the install in early November! Also added 1000cc injectors, closed loop Lamda, waste gate/9 position switch, electronic boost control! Martin is a great guy to deal with and very helpful. Can't wait!

    Apex MPI stage 1 Koso X2

    Just finished install of MPI stage 1(low elev), I have the Koso X2 guage for a/f, temp and boost.
