    Default kpa #`s at WOT

    what should KPA #`S be at WOT for a N/A 383 ls1?
    i can sometimes hit 90 kpa but rarely.
    wot for me is 85 KPA.
    i am wondering if it should be higher.
    i`m using the ls6 intake and stock throttle body and slp lid.
    do these #`s seem low?

    i`m mile high, and key on is 83 KPA.
    i ask because i have seen people with N/A motors hitting higher #`s
    and was wondering if i had a leak.

    You really can't get higher that your key on kpa unless you have some sort of forced induction. Sound like your setup is flowing quite well if your key on is 83 and you have seen 85.
