Is anyone in here looking for bigger injectors from the ss/sc. I have mine and they will give u guys around 25 HP gain with a tune to make sure they are pushing out as much as possible. PM me an offer

 

The injectors themselves won't give you any gain, but they'll allow for more extensive tuning, which in turn, if done correctly, will net you some gains.

I have a set of SS/SC injectors, but I still haven't gotten my car tuned yet, so for now they're just sitting in a box collecting dust.

 

i have a set in my car since summer and the tune is were it is at..when i logged my car before tuning my IDC% was 98% at 6500 rpm i think.i tuned it more to get it down..but the number was still high..therefore i changed to these inj. now im at like 75%..big change..lol, but its all about the tune.

 

Im still running my stock Infectors, just with a few tweaks in the tune I brought the IDC's down to 78% at 7000 RPM's in third gear. Bigger injectors are not need for basic bolt on's.

 

im looking for a set...but to the op you seema little etchy to me...25 hp gain? whered you hear that at? i know thats not even possible

 

Thats a good one. Making a stock tune richer with bigger injectors will rob horsepower.
Agreed.

I'm going to take a guess that some newbie tuners are commanding air/fuel at levels that only a boosted car would require.

 

Psykostevo, you noobie tuner i'm pretty sure he started the SS/SC injectors on a 2.4 thing...

 

Steave did not post in this thread

 

I know, I'm referring to running LSJ injectors in the LE5...he was the first to do it to my knowledge.

 

Yeah he was, I was not sure what you where talking about there for a moment seeing as he has not posted in this thread

 

yea i have the ss/sc n i put bigger ones in and a smaller supercharger pully n made my redline 500 rpms higher and it gave me a pretty good gain for the money.. soo sorry bout the exageration on just the injectors but yea if you want them 40+ shipping i live in NC

 

bigger injectors dont gain you horsepower, tuning them with certian supportive mods will...but in fact, even full bolt ons is not enough to support stock ss/sc injectors in my opinion..the 2.4 already runs (rich?) from stock injectors if im not mistake (could very well be mistaken)

from what ive read over 8 months its that stock ss/sc injectors are only good once u pass t he bolt ons stage and move into forced induction or internals (cams so forth) or ...nitrious???

 

I have full bolt ons, bigger injectors, and a tune, and Im running lean. Luckily I got HP Tuners for christmas so Ill be able to fix that. But if Im lean with bigger injectors, imagine how bad it would be with smaller injectors.

 

I was referring to the comment by Witt

 

According to Tune Time you don't need bigger injectors on the 2.4 unless your boosted. The factoy ones are just fine, its the GM tune thats the problem.

 

yes agreeable..but if doing boosted u need them..but it all depends on how good u are by gettin the stock rich ass tune to run well...thats all that matters..u need a good tuner..end of story...lol

 

so it IS possible to run bigger injectors with a tune to get a gain?

 

Supply and demand.

Think about it.

If you have the demand for more fuel(n20, wild cams, FI) you need to be able to supply more fuel.

The only reason you gain is the tune, injectors cannot add horsepower...you are better off buying a tornado because it will make more power than a re-calibrated tune with the LSJ injectors.

Now if you go into actually tuning the car, you don't want LSJ injectors until you have a power adder, period

Look at the 3rd pic down, he is making 186 whp with basic bolt ons and retuned with the stock LE5 injectors and is at 78 idc.

It is all in the tune.

 

yea i figured just wanted to clear it out because there are a lot of misconceptions about the lsj injectors on the le5

 

so 30 shiped to ny zip 11751 ?? let me knoe lets make a deal aboubt to supercharge gunna need injectors

 

 

40$ shipped man because shipping is going to cost like 5-10$.. i can show you pics too if you'd like
