Is there a company that makes a box for the 04's that does strictly boost fooling?... Or better yet a box that does timing AND boost fooling... wasnt wanting as much power as the TST is capable of delivering. Nor want to spend the money the TST costs. Any help would be appreciated.

Thanks

 

you might want to check out dougs fueling box summary, i think you will find all the info you need pertaining to boxes there.

 

Ive read over the fuel box summary several times... GReat Work BTW... But i did not see an instance where a boost fooler alone was mentioned? Nor any Dyno info on one. Is there anyone who carries just a boost fooler and would a Truck with just intake and exhaust mods really see much increase from a boost fooler?

Just trying to decide where to throw some money... Thanks for the input

 

Barrett,
For the biggest bang for your dollar, you can't beat one of the medium horse-power boxes. As long as you are not out for the absolute biggest, baddest Cummins on the block an Edge EZ, Volumizer, Quadzilla towing, etc. will get you a heck of a boot in the back and won't cause any drivability problems. Any of these will out perform any simple exhaust or intake mod hands down.

Barrett_Fodder,
It's my understanding that all the fueling boxes offered to date have a boost fooler built in. Many of them also have switchable power so that you can turn of the torque/hp increases if you want and just run them as a boost fooler. I would pick one of the boxes that have in cab adjustability like the Van Aaken, TST, or banks.

As for your question about gains from the truck with a boost fooler and some intake/exhaust mods, check out this thread:

Personally, I'd be looking to add intake and exhaust mods so that your EGT capacity is increased and you can really had some power features.

I'm starting to look for the same thing. Just boost fooling so it doesn't defuel and timing to get, maybe, a little performance, and possibly better mileage.
I'm not interested in a fuel pressure increase and I'm not going racing. But a little improvement wouldn't hurt.
Seems ridiculous to open up the exhaust and intake only to find out the computer is defueling to compensate for better breathing. Get outta here!

Wetspirit,

Exactly what i am looking to do ... dodge the defueling that may have been caused by my intake and exhaust. I have thought about the banks or edge boxes for a little more divability that the tst box. I dont need the biggest cummins on the block, but a little kick in the pants never hurt either.

Boss,

What experience do u have with the boxes u mentioned? I see so many on the market it is hard to decide. Any noticable gains in MPG from them? That would be my primary desire as i dont tow huge loads nor do i tow often.

Thanks again

What do you mean by more driveability than the TST box? What driveability issues are there? It looks like the TST is a good unit with no fuel pressure increase, EGT defueling, and digital gauges. Seems to have the timing and boost fooling covered.
It has a HUGE hp and torque increase on the highest setting and I'm a little worried about putting that much stress on things. I know it would be fun but a blown head gasket or dead set of clutch plates in the tranny would be a bummer on a truck that I intend to keep and use for a long time. I wonder how the Cummins can put up with so much torque increase at only 1700 RPM!?
I was able to toast my tranny in my '93 CTD with a stock engine on a long hard tow.

By "drivability" i meant maybe not taring my truck in half...lol...

I suppose a certain amount of restraint would keep me in the sane power range on the TST say maybe 4/3 or 3/3. I was under the impression that TST was having some problems with throwing codes. I know they were working to minimize this. Have they made much headway? And whats a good price on the PMCR?

May have to break down and buy one....hehe

you're right, guys, there is no box TODAY that does just btiming and boost fooling. that might be what your'e looking for. Short of that, a home made boost fooler can be made for probably $5 worth of parts, if you're willing to tap wires. more if you have to buy a connector. check the TDR where I posed a design for a boost fooler. its a trivially simple electronics problem.

 

I have a feeling that with the de-fueling issues with an intake an exhaust mod, that the simple boost fooler w/o anything else, would be a big hit for those that don't want to worry about the warranty issues associated with even a mid level hp/torque box. If someone who had the know-how, and could put together (with comprehensive instructions) a smimple boost fooling only "box", could make enough $ to help support his/her habit.

I guess what I'm trying to say is that I'm sure there are enough out there that have read the post on the defueling with mod's thread that are more than a little miffed to discover that they have LOST hp/torque due to $700+ in "performance" mods. A $25-50 addition to compensate wouldn't be a big issue at all at that point.

Doug,

Could u possibly post a link to your posting on the homemade boost fooler. I would be willing to test build one as i have some basic electronics knowledge. I couldnt find the post over at TDR but if u have plans or can outline how to go about it i could give it a try... thanks again everyone for all the input

 

sure. here is the TDR thread.

 

Excellent post Doug, thanks for the response. Has there been any follow up with the Zener settings IE what knee voltage is required to halt the Boost seen by the ECM to say 22 lbs or so? If i am understanding u right the Zener then would be wired in line with the 5v source wire for the map sensor? Or would it rather be a jumper from that 5v wire to the ground? And is it nessecary to pick the resistor, only to trip the zener to clamp on its knee voltage? am i correct on that one?... Sounds like a fun project. Could be a way to screw off a saturday afternoon just tinkering, good reason to get out of the house...lol

thanks again
