2.8 Stg 2...Maxing out the injectors
 

Ok ive been reading alot about people running GM stg 2 with a 2.8. I know everyone is getting like 130% duty cycle but what does that mean. There are so many people on here that run it and i want to know what will happen.

People always say that what there car is doing but i havnt heard anything about it after that.
Im running stg 2 right now and i want to know if its going to be alright to run a 2.8. Cobalt Addiction says theres works fine. Plus i cant find any 2.85 or 2.9 that fit the GM Hub


HELP POR FAVOR

YOu could ruine your injectors or run lean. I know with my setup im not near that duty cycle. But thats my car. Every car is different.

I noticed you have the pulley boys... do they fit on the GM hub or did you get the new one

yeah pullyboys does fit gm stage 2 hub but how do u ppl know if the car runs lean? wat signs do u c

It fits on the gm hub. this is the one you need. Here is the link.

When I was having my car tuned with hp tuners it was running lean in certain spots.

but since i dont have hptuners how would i c that my car is running lean if i put the 2.8?

Get a aem a/f gauge. They are pricey though

dammit so maybe i wont do the 2.8 lol

Dont get me wrong. I wasnt running dangerously lean. Alot of people are running the 2.8 on the stage 2 with no problems.

You Can, Just have it tuned on a Dyno & Make sure the Guy Knows what he is Doing!:twothumbs

yeah thats my friend told me his buddy is running stage 2 with the 2.8 and no problems so maybe ill go ahead and try it, but is there any physical things i can notice with my car that will show im running lean

I would get a 2.9, colder pluggs and have fun!! I mean the diff getting a 2.8 on S2 injectors insnt worth the risk man. There is plenty of ppl selling 2.9 man... if u want a guys name , i bought one and they look sweet, all polished and 55$ or something

will that fit the gm stage 2 hub? or no

Yeah thats the dude i got mine from!! I didnt get to see it yet man, but my parents told me I got it!! thanx alot bro!! did u do a nice polish job?? :-p

hahaha solid, damn its killing me man, I wont get to see it for another like 3 weeks!! I am away at school right now and exams are starting!! I also got my wheels re finished two toned and cant see those for a few weeks aswell!!

so running at 2.8 wont be as bad if you get it tuned..or does that not matter. I dont want to have to get 60lb injectors but i want a smaller pulley that makes a difference over STG 2.

Getting your car tuned? Doesnt that void the warranty cos your messing with the computer. Doesnt that completly go against the GM kits in the first place

So you make pullies. That is awesome. What could you compare your pulley too? I mean, is it similer to another companies? I will be in the market for a pulley very soon. I'm very picky about quility and won't put anything on my car thats not outstanding. Also, can you order any size you want? For example, something differant such as a 2.86 pulley?
