What would you say if I told you that some people are running 24 lb injectors at 60+ lbs? How about a N/A LT4 running 9.8's with 24 lb injectors? Could you maybe concieve that I am trying to pass on a little bit of real world experience? Save the injector money and buy a good fuel system.
Good Luck,

I'm not trying to disagree with you at all about what you said. I'm just saying there is still nothing wrong with a bigger injector if properly tuned.

If it's a stock LT4, it will have 28lb injectors not 24 last time I checked.

I was always told to add fuel by volume not pressure! That sounds *** backwards. When I had my P1sc procharger setup, I had an FMU with stock injectors. I was told to ditch that fmu and add 42lb injectors. Even with a na 383 I was told to run 36lb injectors, your concept is completely new to me! Im not saying your wrong, but you look at setups done at LPE or any reputable shop and they all go with bigger injectors. No matter if its a cam only car or sick turbo setup. Even the 07 z06 uses 40lb injectors.

I have 84's on my 8.4/1 compression 388 on the stock ECM. No, a stock motor will not gain power, but if tuned right it won't lose any either. It will not foul plugs and be sluggish.

They ARE NOT JETS. The computer controls the amount of time the injectors is open and when. For less fuel it is open shorter periods of time. It will drive the same as long as it is tuned well...
The bigger the injectors the harder low RPM tuning gets because sometimes it is hard to get the injectors to open and close fast enough, hence richer than ideal conditions. THOUGH 30lbs injectors wont be anywhere that point. I have 42# in a stock Lt1 with a lil boost. Runs like it did stock out of boost.
Only huge injectors are said to have that problem.

Ok. You guys win. I am through fighting this one.
The fact that I have tons of dyno time and that I data log almost every pass, have set a stack of IHRA National Records in Stock Eliminator, and can cut low 1.3 sixty foot times in a 3200 lb N/A LT1 car means nothing.
I'll try to keep advice like this to myself in the future.

I was always told huge injectors are a bandaid for a weak fuel system.
That doesnt mean stockers are fine and to just kill your fuel system with high PSI, but just like everything else there has to be a balance.
