could someone educate me on how these aftermarket injector shops rate their injectors? Like how much horsepower would I gain over stock with a DDP2 versus a mach3 or a 370?
I have a 160hp pump and injectors, then get a +75hp set of injectors so Id guess those are lower on fuel than a bosch 300??
do they assume a 215 pump and injectors?
Argh Im confused.

My seat of the pants dyno says I gained some small amount of HP with my DDP2's but the addition of a PS62/12 turbo should clear the smoke with plenty to spare, even with everything full forward. Makes me wonder if I should have got the DDP4's!

 

I believe the Mach injectors (Don Ms) are for the 24v only.

12v and 24v injectors are totally different from each other.

 

We saw a net gain of 75hp with the addition of 370's, this was on a 180 pump with a 4k kit and ACF mods and a rack Plug so you should a gain close to that. And F-1 offers a modified 370 and a Mach 4 12v injector. Both being a hotter injector.
