It wasn't a reliably issue .. Its a rpm issue ... Fuel became an issue at 6200

I installed 72# injectors because of the same problem.

^^ this...

My stock 52lb injectors worked until I broke over 600, then they were maxed out. the ID-850's are only around 45% at over 700hp.

You'll be ok if you stay under 600whp, I have 80lb injectors for mine, but I'm a special case because I also have a wet shot of nitrous.

I would go anywhere near 600 Rwhp on stock injectors nor would I tell someone else to.

He means 52lb ones I think, not stock LS3s by the way. At least I hope.

I hope so, I don't know of any kits that don't come with upgraded injectors. To the OP though, if you can find a set of better injector on here, grab them, install them, and get a tune done. At least with that, you're broadening the scope for more power down the line.

I also think he means stock as in they came with the blower not stock as in they came from the factory when he bought the car, at least I hope that is what he means, lol.

Idk he said stock injectors... I took that as stock ls3 42lb injectors. If you were thinking he is talking about 52lb injectors that makes more sense .I thought you were getting a little crazy there at first with the 600 Rwhp!

I just put 60lb in mine.. I went with Edelbrock and they say they are to 850HP at the crank. I have the Edelbrock supercharger. I also put a ZL1 fuel pump in. I didn't think they would handle it be my tuner told me to look it up and I did. Not bad for the money..
