I don't have the cash to get it tuned right now since i've spent a lot on her already last month and christmas is coming up. I'm tuned with the stock 24lb injectors and was thinking about putting ls1 28s in. Would a 4lb increase be enough to require a tune or should i stick with the stock size?

 

About your injectors =)

 

So if the flow rate is the same it really doesnt matter then? I bought some new 24lb. It's tuned for it so it'll be a quick swap. Man i dumped some money into this thing in the last 3 weeks but hey, better than a car payment!!
shocks, opti and harness, wires, ICM, coil, and o2s. $800+ in the last 20 days.

 

As stated, 28# LS1 injectors flow the exact same as LT1 injectors. There would be no reason to change them.

 

Rather than replace them, why not send them to a company such as Fuel Injector Connection, who will completely rebuild them, test them, provide flow data back to you, as well as a 3 year guarantee? All for less than a new or rebuilt set of injectors. Just a thought.

 

That'd be great if it wasnt my DD. She cant be down for mor than a weekend.
