    Lsa maxed out

    How much power can the LSA make with factory injectors, headers, cats and exhaust before its maxed out?

    11.3 to 11.4 @ 125mph (11.5 @ 127mph in the manual) with a chiller, reservoir, 14% overdrive and pod filter.
    Don't go off dyno numbers because they are all from disneyland.

    Max the stock injectors can take is 14% over drive at that point injector duty cycle is nearly tapped out.

    Looking for colder IAT's? we have achieved 11c IAT2 on a 41c day and -8c during winter.
    We have proven cabin AC vent temps are better than GM spec, both IAT2's and vent temps are all on video with nothing to hide.

    Thats interesting. The car I bought has pod filter and top pulley done. It was apparently tuned by C&V and they said mid to low 11
