have heard lots about them for the trannsmissions and TC but what about them for performance work. i am looking to them for an install on f1 mach 3 injectors, mpi twin turbo setup , 4" exhaust and fass fuel system upgrade.

wondering if anyone has any experience with them. how was their service, how were they to deal with.

spending 20 k between complete trans and twin turbo setup you want the confidence.

 

DTT has proven to work in high HP trucks. Fill in your sig so we know what year truck and upgrades u have. We can help out better from their.

 

My truck is an 07 5.9L auto. it is for now completely stock under the hood.

any help would be appreciated.

thanks in advance

 

Ok first off lets clear up you will not be running F1 mach series injectors. On F1s site your truck is listed under Echo Common Rail so you will be running Flux injectors. Great choice, MPI twins great choice, DTT trans great choice, Fass great choice but may want to look at a mechanical pump (Mitusa/GDP) and one thing I dont see on your list is CP3 upgrade or Duals, PPE great choice.
all in all sounds like a great truck, alot like mine so of course its awesome .

 

go with 5" instead would be my advice

I went with DTT in 03, when I knew a lot less than I know now.... because they had no negative reports on the threads. 120,000 miles later I have never regretted my decision and would do the same again!
Since that time there are other after-market tranny companies that also get good reviews but you can't go wrong with DTT. Nice people to deal with at corporate..... but your local installer is the key to your level of satisfaction!

I personally would have no problem having DTT do those performance items in addition to their trans work.

 

RyeThomas is there a model of Flux injectors that i should be looking at? and same question for the MPI twin setup. Also more info on hte mechanical pump please. what is a "PPE"


rustyshakelford will the 5" not drone too much? and will it do anything for performance?

i'm convinced on the DTT tranny...now just have to get the truck out of the stereo shop so i can get the go-fast part underway.

thanks again guys

 

It all depends on your goals and needs for the truck. 1- are you going to tow heavy and often? 2- how much HP do you want?
The twins will also depend on towing or not, and size of injectors and HP goals. Fuel pumps are great (Fass/ GDP) etc, but for big hp alot of guys are running mech lift pumps, worth looking into. And lastly you will need at minimum a cp3 upgrade with twins and injectors, you can simply upgrade your pump from (Floor-it, Industrial Injection) or go with two pumps (PPE dual fueler, or some other twin injector pump company).
Their is a ton of info on the site and the search area can give you a more than enough info on everything above. Do your research and you can build a heck of a truck the first time, unlike me. Good luck, Ryan.

 

i have a single and 5" and dont have any drone except at ~1400 rpms. not to bad though. with the twins, i dont think you would have alot of problem though. im sure someone will chime in. 4" is said to be good for up to 500 hp. with your planned mods youll most likely be above that, so the 4" could increase your egts where the 5" would allow it to expell the gases easier

I see this reported a lot, but don't agree. I know several CTD's that were in the 650-700 hp range that went from 4" to 5", with no noticable difference in EGT's. My experience was similar... no reduction in EGT's going to 5".... but they sure do sound better!

i tow occasionaly up to 10k, i mostly drive unloaded, i want as much hp as possible and still remain reliable and daily driveable. i have a heavy right foot but, i do not abuse my trucks.

i have been reading about dual cp3's and they seem like the way to go.

also if i go with performance twins rather than towing, would i be dissapointed when i do tow? or would i just have to be more careful with the EGT's.

would i be better off to go with bigger injuctors right away and have the option later to turn up the boost?

thanks

 

Go for it,it sounds like it will be a strong truck!

 

the higher the hp, sometimes means the reliability will suffer. also there is some extra work with tuning and maintence with twins.

if you want something that will pull great and be reliable, i would look into some towing twins(im sure MPI has something) maybe some small F1 injectors (1.6 i think is the milage ones) lift pump, smarty(should incorporate pressure more soon) and you already know what you want for the tranny.

that would get you a reliable 500+ hp DD with great street maners. the performance twins might be a little laggy compared to the towing ones.

just so you know im a moron
