Thanks, TDR Staff

I Just wanted to share my experience with DTT

F.A.S.S Fuel Systems

With the VB and TC I'm looking in to making the jump to injectors and need some help making the right choice, DD2's or DD3's. I pull a 22' travel trailer 4-6 times per year, otherwise the truck is a daily driver. I obviously want the DD3's.



Also, I was set on DD's but see the EDM discount posting. Any thoughts on preference would be appreciated.



Thanks
 
I tow w/ DD3's and love them.



Almost was swayed into the 2's because some people said they had EGT & smoke problems w/ 3's while towing. Glad I made my own choice, & opted for 3's.



Of course after getting them the EDM's started getting popular, but I went for the proven DD's.



It seems most of the EDM users are very happy, and especially since the group purchase is on, that may be the best way to go.



Either way, make sure you dont cut yourself short, and get the bigger ones first.
 
IF you check the dyno graphs of the DDII's vs the DDIII's, the torque comes in about 500 RPM earlier, and both HP and torque are VERY impressive for the III's - IF the engine and drivetrain can take the hit...
 
Don't waste time with honed injectors.



Having installed a set of EDMs today (not in my truck, in someone else's), I can say that the EDMs are fantastic.



The Mach 1s we put in were every bit as strong as my DD2s, only with zero smoke. The truck LOVED them, as they made the thing run like a dream with almost INSTANT pedal response.



I was floored by the comparison of the Mach 1s to my DD2s. The mach 1s are rated for less power, but they feel every bit as strong as my DD2s.



Now I am REALLY curious about what the bigger EDMs are like.



Look at the cost of upgrading to the EDMs. You'll see that the cost difference between an EDM and a honed injector is EASILY a better value because the EDMs are just so much better in every possible way!



A small set of Don M injectors can be had for almost the same price as some slightly larger honed injectors, but you will be MUCH happier with the EDMs.



I can't WAIT to upgrade to EDMs!!!! The only question now is how big!



if DD3s are $600 and Mach 2s are $800, then the Machs are IMHO a better deal by far.



The difference was especially noticeable up here in the rare air (6K elevation).



Though I have generally been pleased with my DD2s, I can't recommend honed injectors in good conscience, as I feel strongly that the EDMs from Don are a much better value at any hp level.

There is no doubt that the EDM's are the ultimate injector right now. However, the DD's are proven and will do a fine job also. There are some deals to be found on the DD's. One might want to check the classifieds... ... ... ..... hint, hint. :D

I ran a set of DD3's for over a year. They made good power, and at the time the satisfied my need for speed.



However, I now have a set of Mach 4's. These sticks flat out move some fuel, and they dont have any of the common drawbacks as 150 HP E. H. injectors... loapy idle, poor milage, and excessive smoke.



The Mach 4's smoke less than the DD3's did at lower boost levels and putting around town. However when you put your foot in it, they really sink you back into the seat.



A few local guys here are running Mach 2. 4's That is about as high as you want to go for a truck that sees heavy towing use, and even then the stock turbo will not be able to keep up.



If you want to keep the stock turbo, 1. 5's will work great. Mach 2's will require a turbo upgrade. Mach 3's will need at least a HX40. Mach 4's need more than a HX40.
 
I ran DDIII's for over a year and now run Mach 5's. There is no comparison as they are too very different injectors. Pulling with the III's might get a little toasty and you might have to do other mods to correct this. I have heard comments from guys runnng the EDM's that they see lower egt's with the EDM's. I might try the Mach 2's especially at the group prices. :D
