The cam isnt in it yet and the port and polish job could have been better just installed the new intercooler and noticed some huge drops in egt's, ill be taking it to the track this next friday woot woot. and since those #'s ive gotten a cam intercooler and still workin on the twins gunna try to beat some other red dodge out there and honestly the idle is kinda a hit and miss my first pump had a lil less of a lope than the second but the second newer revision feels more peppy but they both run smooth as silk with a load, and congrats on gettin one bud!! also for the rough idle i found that the fluid dampner smooths the truck out considerably soo if it is to much get one and the lope is still there but not the rocking and rollin

whats up guys? ya i was hoping to break 600, but im really happy getting what i did! been trying to break 500 on the limited budget ive had for the past couple of years till i bit the bullet and got this monster pump.. like Cliff was saying, after the dyno, my pump was hit or miss with the idling... Zach rode in it before we hit the dyno and ya it was pretty lopey! but i like that kinda stuff so... what i thought was really weird when dynoing was that i made the most horsepower with smarty on 4 and drag box on 3 when i set it to smarty 4 and box 5, i lost 40 or so horsepower.. then reprogrammed smarty to 8 and drag on 4 and put down 5 horsepower less than the highest number... any input on what went on there?? my only guess is too much timing, but i dont know...

im thinking i need to just suck it up and just spend an hour or so on the dyno with this pump to see what works with the pump as far as smarty and adraline. i hit 605 with the adraline on 8 so maybe i can get more

With this much fuel delivery what are these pumps and injectors doin to your EGT's. I'm assumin they are not designed for real world pullin a trailer applications.

If you've got enough turbo they'll do fine towing. You can turn them down just fine. I'm sure a good 62mm turbo would do egts fine as long as you didn't run anything other than timing to the pump.

i bet with twins and water methanol, the pump would do fine on the street, anybody daily drive a truck with one of these monster pumps in it??

and heres my question, they reccomend running their injectors, will my DDP 150 horse injectors work okay with this pump, or do i have to drop the dime for their injectors?

I will be daily driving my truck with it. Brandon (grim reaper) drives his daily as agressive as it is. His EGT's Wernt that bad just cruising on the highway but i wasnt in the truck when he ran it.I'm not sure how it would do to be doin realworld trailer pulling. My guess would be that this is not for that kind of a setup. I hardly ever pull a trailer with my truck and i'm getting a once in a lifetime deal on my pump which is why i'm doing this.

will my DDP 150 horse injectors work
No. There was a big argument once between the pump vendors on what would work with them and it came down to if you want the warranty you have to use this custom injectors. Brandon was running the Superdragon 270hp 10 hole and Mike the builder said that they would not work. Cliff ran a set of DDP's for a while and it ended up badly, but the good news is he is back on the road goin strong. And come to think of it...What were those injectors that killed your first pump Cliff? I felt for you seeing thos pics.

I think it's something to do with the internals or something or other of the injectors.
