So I just dropped my pulley from stock to 3.4 and I'm reading 2.6 knock at full throttle. Obviously I need a tune, but was thinking, maybe I should do a bit more to lower my kr before I get tuned. I do not have ubend deleted and am also going to do that, but im thinking my next mod should be an upgraded TB. So I need a bit of advice on my options between zzp's stage 1 TB, zzp's stage 2 TB and Northstar TB. Now from my understanding a N* TB can be found in caddilacs. zzp's kit sells for around 300. am I better off going to a junkyard and pulling one off a caddy? If so, does it matter what kind or what year Cadillac? Also, my supercharger is a non-ported gen 3.

 

TB isn't worthwhile enough to lower KR. People only go to the Northstar to run a different MAF sensor if they out-flow theirs, which you won't.

Get a tune before you crack a piston and don't have an engine anymore

 

Well Im hoping to cam as my next power adder here i'd say mid march or early april. People have told me to wait until i cam to tune. I dont daily drive my Monte but deff. will get the tune here shortly. Just wanted the extra advice on small mods before i tune. Would you also recommend tuning now and worrying about mods such as ubend delete and upgraded TB later down the road? I just dont want to have to re-tune for a mod that simple you know?

 

I would put your stock pulley back on, do all of your mods THEN drop the pulley and tune.

 

Yea...dont know why i didnt think of that Thanks chibi you're advice is always appreciated!
