Default stage 2 ddp vs 370 marnies

Which injector is better? I know the marines have the wrong pattern and are smokey but I still feel that they make better power then the stage 2 ddps which are 75hps and the 370s are 90hps. Any advice good or bad.

You have "better" and "better power" both as questions...which is your bigger concern? A hot smokey injector may make more power, but that does NOT make it the better injector. Hot and smokey are two potentially catastrophic side effect to endure in order to make a few extra HP. The BETTER injector would be with one that makes more power WITHOUT the detrament of excess heat and wasted fuel.

That being said, I think there are still better options than either of the aformentioned...

i have the 370 marines in my 96 12v they do alright very smokey and they do run hot i am soon going to switch them out for ddp injectors just so i dont have a constant haze of smoke while cruising with 900 to 1000 egts

if im not mistaken, I very well could be, I believe the ddp stage 2 injectors are just 370 marines stamped with ddp logo
