So what size next??

[The Ripper973]

Just got done putting my ssic on my gtp and I have absolutely no knock at all on my 3.4 pulley with 17ish for timing at wot. Current mods are
Ssic with ported lim 3.4 pulley
Headers with a zzp catback
K&n intake
Plugs are NGK tr6 gapped to 0.53
Zzp pcm currently might be ordering an hp tuner

I'm wondering if I could get away with a 3.3 pulley possibly or mabye even slightly a 3.25. I would really only be running it at the track. Most of the time I will be keeping my 3.4 on. I do have an aeroforce to scan. Highest octane on the street I can get where I live is 91. The track I can get 104. What's your guys thoughts?

local here was on a ssic and a 3.2, i tuned him to 18º wot kr free. 3.2 pulley is about maxing the stock injectors, id not go any smaller.

install 104 plugs gaped to 0.50.

Might look into a 3.2 then and look at picking up a new set up plugs. Thanks for the advice Scotty. Wouldn't be where I am without some of the people on here.
