    Big enough injectors?

    I found a deal on Gm 28.8# injectors for 50 shipped. I was told before that my truck has the 19# ones stock, and with plans shortly of having spray I don't want to risk leaning out. Are these worth the money to buy? also would I need an instant retune for them, or could I wait a little bit? Thanks.

    Save up and buy 42s which will be direct replacement. Then you never have to upgrade. Well not never, unless you want to really spray. But I sold TxStVanWilder 42lb injectors and hes cammed/sprayin 150 shot and he is fine.
