Ive been getting some kr up 7* when in boost, esp around 45-60mph.Under wot and half throttle, I changed the plugs running 104's gapped at .050 and still getting the kr. Do i need a tune or am running the wrong plugs/gap for my mods?
zzp stg 1 tb, 3" dp, 2.5 catback exhaust, dhp pcm, 3.4 pulley, slp sway bar (flipped)...any ideas?

You need some AL 605s, a 3.6 pulley, and a real tune.

3.4 is to small

Pulley is to small. What year and kind of car.

What other mods would i need to support the 3.4 pulley? Headers? I/C? Its a 99 regal gs

Headers will do 3.4.

Not necessarily, I'm still getting KR 2-6° on the following mods. Can't get it to go away for the life of me..
00 GTP.......Reptile DHP ecm, ported SC, ported and blocked LIM, SD headers, 1.9 Harland sharp rockers, HAI, Flipped SB, 105#crow springs.

My first setup consisted of a 3.4, headers, intake, 104's, 180* stat, 1.9 rockers, overkill tune, etc. and I still had up to 5* KR at times.
As others have said, you need to pulley up and tune.
