3.7L Burnout and Acceleration Video's.
I have the 19# injectors. I can't believe how much the truck woke up with the injectors and DIY CAI and exhaust. Now I just have to install my Leveling Kit tomorrow and I will be set! (Thanks Donkey!)

My bad man, I totally missed that. Have you guys read my boost accessories thread in F.A.Q.? I have an entire article on it.

The Cobra SVT injectors will work with the 3.7L and the 4.7L. They are a direct swap, simply pull out the old injectors and install the new. They are #39 injectors on the ford fuel rail/pump and around 45# on ours. In my F.A.Q. I've even got the part numbers for anyone who wants to order them.
JTEC 4.7L injectors 22.5#
NGK and JTEC HO uses 24#

Here's my question: what size are the stock 3.7L injectors? If you go with slightly bigger injectors than stock, the ECU will compensate global fuel, LTFT, STFT, and pulse width accordingly. If you go bigger than "slightly bigger", then you will see issues (running too rich). Fuel pressure can only be changed if you have an adjustable fuel pressure regulator.
Now, the power gains and throttle response increase you are speaking of could be related to the style of injector difference between the Ford and Chrysler injector (spray pattern). So, to recap: my assumption is that the Ford style injector has a more efficiant and performance related spray pattern vs. the Chrysler style economy injector.

Ok, so the size of the Ford injectors are the same. My initial diagnosis was valid. You are seeing the enhanced performance because of fuel/air atomization. The Ford injectors must have a better spray pattern.

Bosch 0280156127 42lbs/hr at 43.5 psi
That's a lot of fuel considering the stock is 19lbs
