I will disagree with that statement.The Marine 370 is probably the most under rated injector out there for our 12v's and plenty of power can be made with them.You do have to understand what the limits of the injector are and know that you shouldn't run much more than 20 degrees of timing with them,and even that may be a tad high.Another thing you need to understand that most all injector comapnies that make 12v performance injectors use the Marine 370 as their base,except for SDX which uses a new nozzle with the proper spray pattern.This was one of the reasons my new out of the box DDP4's were sent back and never ran as they even had the marine part number on the body.I have seen 792hp on fuel alone at one of our dyno rips made with a set of 370's.

Here is the video of my truck from this weekends CPDI Open House dyno roll.Please be kind on the narration as my buddy didn't realize when he was talking it would be heard,LOL.

Dan...
I did actually take a bunch of low end fuel out of my truck for this weekends runs as I was trying something to see what happened as my pump has alot of available fuel.It made 9 less hp than my Spring dyno roll but made 150 ft lbs more torque.The smoke stayed constant and one color which it did not do in the spring.I have decided that the spring roll was a combination of a couple of things,winter fuel blend and the truck trying to put the fire out due to way to much low end fuel.I do not think I have enough charger to ever clean up the fuel I have between the pump and the 5x.014's and am chatting with MADP about hanging a set of twins on it.

Believe it or not Dave,it was down a bit from spring and only made 522hp.The torque was up a bunch and was 1051.The key here was taking some low end fuel out had it make max power at 2500rpm and at 3200 when we lifted it still was making 490hp which it hasn't done since we did the pump install a long time ago.The air was not in my favor either as it was 75 degrees and was 100% humidity so I was pleased.Its needs some more tweaking and a bit more timing and we will see what happena at the Carlisle Mopar show.I was thinking about trying my hand at the NADM show next weekend but no upwards exhaust and I can not find a set of loops to borrow so I will go down and spectate.

Nope....
Keep my 66/71/13 up top and drop a S480 with a race cover down below.
