Small blind play, tourney vs cash differences

[omaha]

Evening all, i am up 40%roi at stars 6-15 dollar tourneys, so have some idea of how to play.

Have started playing $ games at party, .10/25.

In the tourneys, when folded to me in the sb, my default play was to raise 3bb, bet 4 on flop regardless, then consider my hand (ok, maybe not everytime, but certainly until some1 played back at me)

Doing the same thing on party $25, and just looked at my stats, and i am getting KILLED in the sb.

In summary,

Tourney(stars) 40k hands, (7.3k in sb), I have WON .02bb/hand, ie 2bb/100 hands. pf raise 35%, raise first in 30%

$25.6max nl party 6.5k hands, 1.2k in sb pf raise 26%, raise first in 21%, I am losing .3bb/hand, ie a massive 30bb/100 hands

I kinda get the idea i have more folding equity in a tourney (part. a lot of these would be small stack shoves with any2), but am at a loss as to my atrocious blind play.

FWIW, my feeling is the average 25nl party player is a fair bit better than the 5dollar stars tourney players. I also tend to tighten up very quickly after someone realises i am auto raising. Obviously, i get a hand in the sb once in a while, and get paid off well.

I raise or fold everything when i am first to enter, and am playing 50-100blinds deep.

What should i be raising in sb (6max,when all fold to me)? What should i be folding in the sb (obviously a [censored] more than i am atm)

All help much, much appreciated!
