Which DDP's are comparable to Mach 4's(150hp). Which brand runs hotter??

I have the #3 on my 94 & it'll smoke like a freight train w/a #4 plate,let us know if you get them & how they work w/your turbo
I just have a stock turbo w/a 16cm housing & when I blew the hg I ported it & it cooled it down a good 150 degrees

I am thinking the stage 3 would be better for me. I think the stage 4's would be to much. I am also thinking of these injectors http://cgi.ebay.com/ebaymotors/ws/eB...m=260261194443 let me know if anyone else has used them and how they liked them.They are form red oak diesel clinic.

I'd get the ddp 3's they easily support a 500 horse truck depending on turbo, smoke less then my old marine injectors.

I'd run 4's, if it's to much you could turn your pump back some. That way you'd be setup for any future plans.

hm, I like my 2's and will probably like them a little better with a dragonfly pump. at least with a modded pump you can hit the valet switch and make sure youre not pouring out the smoke accidentally. otherwise it takes a lot of fiddling with the AFC to get low smoke.

Auto and a single turbo
I vote for the 3s
