    ok I think im finaly learning something.. i looked at the predefined maths that i was using for boost.. and they were using the map-baro to come up with boost which is a No-No from what your saying.. so i made a new math using boost low res - baro... and bam finaly have working boost to make a histogram with and can clean up the charts with just working boost gauge like you were saying....doh !

    I know this is a really old thread but it has great info from Cobaltssoverbooster (as always). Mayhem, did you ever figure out what your issue was and why you couldn?t get over 18 psi?
