Ok so my offset is 47 and my target load is 86 at WOT, which sums to 133. I'm hitting ~26psi of boost though, so someone explain this to me, since everywhere I have read it seems to indicate that a total load (offset + target) of like 280+ would hit 26psi not 133. Does a 3port make these numbers basically meaningless and you have to work from the ground up?

Sounds like you are PSI based tuned, not Load based tuned. Don't look at the numbers in your Load tables, as they won't look right.

47 in Target Load means that your Atmospheric Boost table reads 14.5.

Normally Target load tables are 80+.

Very interesting. I retuned it tonight as load based - although I swapped back to PSI based, I was just trying to learn on my own. Golden, do you do PSI based tunes or load based, I heard lots of people went to PSI but changed back to load for one reason or another (though I can't recall them). Any thoughts or input?

I use PSI based.

PSI

I know this has been covered but just so I'm sure, you guys use psi based because it's easier and no one tunes so on the edge that you'll blow your motor with another 20 or 10 WTQ?

Yeah. If you are within 10 tq of blowing your motor, it will probably blow anyways.
