Hey guys, I need your thoughts on something.

I am installing Stage 2 (injectors, pulley, belt) on my SS SC on Thursday myself, then driving her from Sylvan Lake to Red Deer (approximately 26km) to have the GM dealership update my tune. Do you think it will be a problem driving the car that far on the existing tune?

Thanks.

 

Yes do not do that it will not run right with larger injectors if at all. I would have it towed there if it was me.

 

install the pulley and belt before then drive to sylvan, then just swap out injectors there. ( Will only take 10 minutes in parking lot) The pulley wont effect your car that much, just dont go heavy into boost

 

yeah man drive slow try to stay out of boost and im sure u could have injectors in just drive it a nicely as u can trying to stay out of boost

 

If you put the injectors in you wont be running right if at all. putting in larger injectors may make it run too rich to start dont do it.

 

althoug I don't know much about modifying the LSJ cars - I'm inclined to agree with these guys on the injector comments;

your fuel tables are all going to be based on the injector you're currently running - and your car ecm will not be able to compensate for the larger injectors - just swap out the injectors in a parking lot across the street (or directly infront of) the dealership doing your reflash.

but that's just my $0.02

 

It'll run fine. I bought my GM Stage 2 kit when it first came out... and my dealership didn't know they were supposed to flash a new tune on my car. I drove around on the stock tune for a couple days... even took it to redline a couple times (that's how I found out they didn't flash it).

The car will be fine. I guarantee it.

 

Not sure if u went gm kit or aftermarket stage 2 so is it 42lb injectors or 60's. Not sure about 42's but if u put 60s in without tuning it, the car will start but then die. Me and my tuner wanted to see if the car ran with 2.8/60/belt and no tune...car sounded like a truck for a few seconds then it stalled out.

So in other words, like some already said, do the pulley/belt then drive easy and stay out of boost then when you get there swap the injectors. Swapping 4 injectors should only take 10-15mins.

 

let me think, hmm stockers are not 42.5s so therefor youll be sending alot mroe fuel in your combustion chamber so threofr your can wash your sylinders, so dont do it bro!!!!!!!!!

 

Some of you people need to shut up... because you really don't know what you are talking about.

Well, he said he's going to a dealership to get tuned, so I assume that means he bought GM Stg2. The Stg2 injectors aren't that much larger than stock, so you can get away with running them untuned for a while.

 

agreed, the larger injectors wil initially run rich, but the car will trim out a lot. stay outta boost for sure.
you can drive it the 20 kms at 2k rpm with light load. the 32 lb to 45 lb, is richer, but not near as rich as the power enrich setts the car has.

 

why people do that, i will never know. GM Stage 2 is pointless. Only reason you would want it is for the warrenty, but since he is doing the install himself, his warrenty goes out the window if anything happends. He did the install himself, might as well go to a tuner with hp tuners and get a good tune.

 

Exactly.
