Edge can turn your comp box 120hp into a drag comp 140 hp with no defuel as 2600rpms iirc

The B-D RAD gets rig of the CTD's torque management at low rpm. A good modification.

Also there is the CaTCHer ECM available from Marco.
PM Bob Wagner at www.nwbombers.com for more info on that one.

Talk to Pat about the DragComp.
Or simply send your comp to edge and have them upgrade it.

Greg,what yr is your truck,a RAD is only needed on 2001's and 2002's. Cummins caught onto us and installed programming to limit boost to 14psi until your moving a few mph. I recommend you not get the RAD box unless you have installed both billet input/and output shafts .You can easily snap the output shaft doing a 4wd launch at 20psi in some cases.As for stacking boxes,no you cant stack anything with a comp,just do the ungrade to drag comp,and you need to address your lift pump before you do that. Sell the DD3s ,and get a set of Don Ms Mach 4's,you will pick up about 50hp,lose some smoke and ,and the idle will be much quieter.The Mach4s are the ultimate single turbo streetable injector.

John, you try the CaTCHer yet?

Evidently it plays real nice with a DComp with the timing removed!

Rock on!

Ditto on the Mach 4's

But.... if already close (with DD3's) why not a set of PDR Towing Twins and a set of Mach 6XX's?

Just for fun of course!

Id do the Mach4s first,theres a lot of HP on the table right now,esp low end HP and Don will hook him up later with an upgrade to Mach 6+ when the time comes.If and when he does twins,the minimum he will need is a set of ARP studds,if hes lucky it will hold.If hes going for it,Id just order a brand new head,o ringed from PDR or Don M. If hes been bombed a while his head is no doubt cracked,and valve guides have been known to wear out in as little as 36K miles. Just put a new o ringed head on it,and be done with it.I love my PDR street twins,and PDR cam,they work well together

well i have a lot of decisions. i think what iam going to upgrade is my edge box, add some diesel dynamics stage 5 injectors, leave the turbo the same because its a really great turbo, same one as TS Performance has, and get a mad ecm. that seems the way for me. i have a 2000 also. i have a fass fuel system now too. and i do have billet input and output shafts. the edge box upgrade does fuel really hard though right?, like to the redline iam guessing? iam 19 years old and i know for sure that iam am not going to get twins because i dont need them or want them. i am going to get the head oring'ed and get studs here shortly. thanks guys, Greg. and how many of yall are going to the TS drags, i wanna meet some of these guys on here even though they drive CHEVY'S! jk:)

Since you have a 2000,you do not need a RAD,i dont like what they do to your cluster,and check engine light anyway.Greg, ill offer a little advice,stay away from the nitrous.Twin it instead. The twins cost the same as a well nitrous system. You cannot build a good system for under 1500-2000(nitrous,with an automaitc heater.progressive controller and 2 15 lb bottles. I have all my stuff off my Dodge, the truck now runs with twins what it did with a B1 single and Nos.but now i have the power anytime i want it.Either way you need to or ring and studd. A big single will run 300-500 degrees higher EGTS than twins.You will eventually ruin your o ringed head with a single and a ton of fuel.Twins are the answer,not nitrous for a street driven truck. If you want the biggest dyno number or absolute quickest nitrous is it.I spend 99% of my time driving my truck,not dynoing or drag racing.Also a 15 lb bottle will last only 2-3 runs,(for a 150Hp gain) and costs about 75 bucks to fill every time. I used to run DD injectors,if you want the most power/least smoke switch to Don Ms.The fastest and most powerful trucks all run Dons injectors. I had 2100 in my N20 system,but i did it right,and its all on the shelf now.After selling my B1 i had 3000 in my twins, i bet i refilled the n20 bottles 7x at 70 a pop. Add it all up.not to mention i spent 15 min waiting for my bottles to be filled every time.if you drag race at sanctioened events alot of them do not allow any fuels or oxidizers other than diesel.So your stuck in the high 12s them at 520hp max.

so when i get the head oring'ed and studded, i can the get some bigger injectors and twins right? and still be fast? i have a bell usb turbo built by pius, could i use that and i hx40 or somethin? or would i have to sell it and buy 2 new turbos? i would like to have something that spooled up really fast and somethingi can still run the quarter in. i dont care about the smoke though, thats why i was wanting some dd5s or dd4's. i like to race alot on the street so i need that fast spoolup like i said earlier. my bell usb does spool up kinda quick but i would like quicker. thanks, Greg
