Would it be safe to run a 75 wet shot and 2.85 pulley on the Gm stage 2 mapping? Im just wondering or would i have to bump up to bigger injectors. I have never messed with Nitrous.

 

If i was you i would run a 50 shot i know my friend DON is running 75 shot on 60# injectors and a smaller pully like a 2.7 or 2.6 i think i may be wrong

 

is he running the GM tune?

 

GM Stage 2 calibration has too much timing for a 75 shot.

 

how do you adjust the timing or should i use a 50 shot

 

you use HP Tuners to retard ignition timing

 

Or get the stage 3 pcm...

 

is that the GM stage 3 flash

 

stage 3 isn't a flash IIRC its a completely separate ECM that is nitrous ready...

 

stage 3 is a new computer. The injector size does nto matter if you are running a wet kit......you will need to pull timing though

 

so i can go the dealer an get that new ecm.

 

Yea, will cost you a pretty penny. Plus you can't run it all the time. And it will disable your AC when you do have it plugged in.

 

why can't you run the stage 3 pcm all the time???

 

Well you could, but it is marked as "Not for road use" and disables your AC. Of course, if your up where it never gets hot I guess that won't stop you. But you better pull it before taking it in to a dealer or right away if you get in a wreak.

 

Why would you pull something that is warrantied? I have the gm stage 3 with nitrous both installed by my dealer. Completely under warranty.

Soooooo...why would you pull it?

 

thought that stg3 voids waranty b/c it being for offroad /track use u sure u warrantied when u have n02

 

lol
i think you might need to read the fine print on that one.

 

Yep, it states in the papers right from GM that it voids the warranty. And nitrous really really really voids your warranty.

 

All of you guys...you don't even have it installed yet you know so much. haha

I have it on my car installed and I also have it in writing from my service tech and his manager in writing. WARRANTIED.

So thank you for trying to tell me what I do and do not have on something you yourself...do not have. hahaha

cracks me up. all these people without the stage 3 telling people who have it what is covered and what isn't. Let me see...I'm 30...I work in legal for the government...pretty sure I am capable of understanding what the "fine print" says.

 

So what, I'm 31... I kill people for the government... pretty sure that you don't have to read the fine print because it is very upfront about it.

*YOU* might have your dealership agreeing to warranty it, but that doesn't do anyone else any good. That is the dealership, not GM. What does that mean? You need to STFU with this it is warrantied crap, since you will get someone who actually believes it is from GM and not just one dealership screwed over.
