Which options would you pick?

 

I'll tell you the options i did pick. I'm paitently awaiting my stage 2 from them. Should be here any day now.

-Stage 2 belt
-M62 Pulley
-7000 rpm
-Cobalt
-2006
-Remove
-No
-Stock
-Email (have a buddy with HP tuners)

 

Personally I would go with the following.

- None
- Oversized Tensioner Pulley
- M62 Pulley system
- 7200
- Remove
- Cat obviously depends if you have one or not
- Throttle body choice depends if you are stock or LS4 obviously. I'm assuming stock.
- If you know someone with hptuners do it by email, if you wanna have your car down until you get the stuff send in your pcm, if you have an extra 100 bucks have them send you the pcm first. Pretty simple.

 

What is the disadvantage of 7400 rev limit, and what exactly is a Catayltic Converter

 

If you are on the stock valve train you could end up floating your valves. I have my rev limit set at 7250 rpm on my GM Stage 3 car, and that is on the very edge of being reliable. I wouldnt go past 7200 rpms if you are still on the stock valve train man.

Juding by your other question you seem very new to modding. I think you would be best to leave your rev limit at 7000 rpms.

 

Yes I am new, but everyone starts somewhere and there's only one way to learn.

 

You are correct. I wasnt busting on you by the way. I only made the comment so your setup will be safe until you learn more

 

Just finished installing the same kit. The guy at the dealership I ordered it throught said 7000 rpm would be the safest having almost everything internal-wise stock. But Couldn't be happier with OTTP stage 2 kit. awesome!

 

Your in michigan call up josh at ottp, real nice dude just went out there n picked up a gauge im sure he could answer all your questions.

 

I was thinking about getting the stage 3 kit from zzp, i have a noob question as well. is the pcm that the comes with plug and play? ill pay the extra hundred bucks to have it send. do i just unplug the existing one and plug in the zzp>? sounds a little 2 easy...

 

than you will HAVE to go to the dealership and have a crank case relearn done , than have a private tuner fix your idle issues and running crazy rich issues.
