99 Regal GS, which pulley to run?

[Frostflowz]

Title, I have a 273,000 KM regal. New built trans, 2400 stall converter, speed daddy headers heat wrapped, full 3" out the back with a cutout mid way. Homemade 4" fenderwell as well. ZZP coils, wires, and tr6 plugs.

 

According to the zzp website I can safely run a 3.4. However for the 3.3, it specifys I could run that one as well...

 

This is a daily driver, more power is cool but keeping it tame is not a bad idea either. Which would you guys choose?

 

With that also said, which gauge will I need for keeping an eye on KR?

 

As for a tune, I have looked locally and they are all very far away from my budget.... I hear Overkill is one of the better ones.

 

 

Any help would be great, thanks

with a good tune you could prolly get away with a 3.4. i wouldnt put too much stock in zzps recemendations. you prolly wont get anyone recomending overkill here either. i guess he burned some bridges a while back here

aeroforce scan gauge for kr

I would run a 3.6 if you aren't getting an in-car tune. Running a 3.4 on a canned-tune with your mods will probably have a less than desired timing just to be safe.

 

Also, always have a way to scan for KR.

Being higher mileage i'd start with a 3.5 and monitor KR there first.

I'm in agreement with the 3.5" pulley. You're not going to get much benefit from any smaller of a pulley without a proper tune.

 

Power costs money, and unless you're willing to spend coin on the inevitable engine and transmission failure, I'd keep it mild.

I can't argue either, like I said this is just my daily, however I would like to get all she's worth, you know? The transmission is fully built now as it did crap out on me so I spent a little extra.

 

It doesn't need to be rocket ship fast, that's what my 72 gmc is for! However, I would like to put the lay down on some g35s and JDM stuff around town during my daily commutes that like to think they're fast =)
