Are the ddp3's worth the extra $250 over the sdx 5x.014's. They say the ddp's will add a mpg, what will the sdx's do to my mileage? Let me know what you've experienced!

 

I'd try the SDX's. Have heard good things about them and their prices are reasonable. Not sure what size the new DDP3's are though. The old DDP4's were 5 x 13.

 

I think the new ddp3s are the old ddp4s... I think.

 

i have sdx 5x16 and theyre a great injector. if im easy on it i get good mpg about what i did back before i modded the truck. they create a lot of power and are very very clean injectors also. nice guys to talk to

 

Both are good injectors. The DDP's are the best I have ever seen for mileage.

 

You can get the DDP3's for 674.10, pm me if you wanna know where. Or if you know somewhere cheaper let me know please.

 

FWIW, The DDP4's are good clean injectors.

I've no first-hand experience with the SDX units but Smokem carries on like he knows what he's doing.

 

Old "DDP4" Is equivalent to the now what is called "DDP3"

 

I loved my "old" DDP4's until my local shop destroyed them. I'd still be running them.

 

Are the sdx's a good daily driver?

 

I'd do sdx personally. I've yet to see a complaint plus it's a larger injector for less money.

 

Diesel Auto Power has 5x14's for $540
I'm doing the 6x12's for $530


i hear great things about ddp, but its a lot more money

 

I like my DDP3's (55mlph). I've Never ran the sdx's. Heard great things about both but spent the extra money for the company that had more "on the street" word of mouth It was worth it to me. Plus I was coming from marine 370's so it was a world of differance in smoke, power, and drivability. Good Luck with your choice either would be good.

 

I would love to compare the SDX to the DDP's I have. Pretty sure I have the older ones 4's because I was the 2nd person to get them and they are still working great in my truck.

I am due to pull them and have them cleaned and pop tested in the next couple months.

 

Are the new DDP 55 lpm 4 or 5 holes injectors?
Does anyone know what kind they are too for that matter; sac or sacless (voc) type?
