and i have my 60lbs injectors on the floor next to me
can i install them myself?
or do i need to tune the car (witch i was planning on doing at a later time anyway)

 

don't put them in untill you'r eready to tune.

 

I dont see why just installing them would be a problem. He's stage 2 on stock injectors right now... anything is better then stock, besides, doesnt stage 2 come with a pcm or something to add more fuel?

 

pls. dont.

 

i dono.. i dont see why not, such a minor mod imho....

i dont see why he shouldnt, stage 2 with stock injectors, i dono , id imagine anything would be better then maxing out the stock injectors.... common sense kinda.

 

Bad idea. Most likely your car won't run with them well if at all. You can try if if you don't believe me but it will be a big hassle when you just have to switch them back.

You will have twice more fuel all of the time. It just wont be good. Imagine AFR's of 7:1 instead of 14:1 @ idle and @ wot you will go near 5:1 It's just not good @ all.

No they are calibrated differently. Won't work.

 

again.. stage 2 pully on stock injectors.. it makes NOOO sense not to add more fuel.

last time i checked id rather my car run RICH then lean. what do i know..

 

i went from stock to 60s with a custom tune so i cant say anything about stage 2 tune but my car certainly wouldnt start with the 60s in it before it got tuned.

 

why do u want to run stock injectors ona stg 2...doesnt stg 2 come with 42.5 injectors???

 

well i understand it would be dumping fuel but what if right now its running super lean? i dono

dana step in, its your car lol i dont even own a cobalt, im just assuming what seems right.

 

i am just guessing but i think he bought the pieces seperate so he has gotten a pulley and a plug in tune so far and has went with 60s instead of 42s for injectors.

 

i bought the car with a 2.8 pulley and Green injectors, witch iv heard are stock,
i have the plug and play next to me with the 60lbs injectors
how much more damage can 60lbs injectors do to my car that the stock ones are doing?

 

go ahead and plug those injectors in.

Good luck starting your car afterwards.

 

my advice since i dnt have an ss.sc...take them from the other ss/sc guys dat has experience with stg 2 and bigger injectors

 

Not too much from what it seems. The said car is tuned for the 32 # injectors. It's running good until 6k. Yeah your right its better to be richer than leaner but we are not talking about a little lean or a little rich being the difference.If you put the 60's ion it is twice as much fuel all the time. all the time. the car probably won't even run to be honest.

But if you really don't believe me than try it. Within 30 seconds of driving it you will see something is wrong and you will change it back.

 

i have been reading some of your posts lately, may i suggest,



yo.

 

Why are you so insistent on not taking the advice of people that know? It is not plug and play. It's plug and tune. The PCM in not calibrated to run 60lb injectors.

 

i dont own a cobalt.. i just didnt see then sense in it thats all. I just figured there was a pcm or something already that would just tell it how much fuel to use. apparently not, like i said, i dont own a cobalt of any sorts.

just thought it was common knowledge. I know my car wouldnt run with any sort of inj. upgrade. hell a cai can blow the motor! just thought cobalts were as easy as srt's or something... they both cheat haha

 

Some things are just not plug and play. Injectors are the perfect example.

 

staged injecors are plug and play... thats why i say cobalts and srts cheat lol i didnt realize 60# wernt a staged product.

 

what kind of car do you drive

 

Dude why are u giving advice when u have no idea what ur talkin about and the whole fact u dont have a cobalt could be a issue...

 

how is it stage 2 if it has stock injectors and no tune?
