What I am working on for the 6.7L PMT as far as fully adjustable tuning will eventually work for the 2003-2004 Trucks as well. We most certainly have not forgotten about you guys. We are not offering Crazy Larry to anyone right now because we are trying to get our ducks in a row to ensure we can keep offering race tuning solutions for a long time.

I am sorry to have to keep saying this, mainly because I would like the restraints off more than anyone, but we all just have to be patient and work with what’s out there already……for now.

buddy, is it true that there is something in bd's tuning that doesn't allow it to work with a boost fooler, and would it be the same with quadzilla as well as bd's boost builder?

Jfaulkner

I don't know why it wouldn't. I used mine for years with a TST (tst was mostly off but acting as a boost fooler) without problems.

chipmonk

earlier in this thread, some people said they were having problems with their bdtd's, when using the quad boost fooler.

I had problems with my triple dog and a quasd race box but at the time I was trying a new program so I could not tell which one was having problems

Bud did you get my PM?

The more Ive started reading the more issues Ive been finding with running the bully dog and the quad fooler. I guess they really dont play nice together. I tried unloading and reloading quite a few times and nothing has changed. Anything else I can try?

If a boost fooler is doing its job and capping MAP readings, the program in the ECM cannot see the boost that the boost tables are expecting. It's not surprising to see that some have issues with this setup. Perhaps it depends on where the boost fooler is capping boost? 18psi, 21psi, 28psi? That would probably affect fueling.

I had similar experiences with stacking a TST and EZ. If the EZ was plugged into the MAP first, the TST would never see over 21 psi and never fully fuel. Swap connections and it was a whole different animal.

I had the opposite result running a MP-8. It has an uber-cool MAP strategy that shows the ecm MORE boost than actually present at low boost to trick the ECM into fueling sooner. Stacked with a TST or Smarty it's plain SICK!

Anyway, my point is that the variable may be in the boost fooler, not the program.

Ok now I am starting to get really fed up. I took off my quad fooler and it seemed to run a little smoother at first. All was well and the next day she started rolling a little more coal like she used to. So I take off my puck and try just Crazy Larry. It felt completly STOCK. No smoke and quite a dog around town. So back goes the puck and its back to normal, more smoke and power than just the puck alone. This lasts for a few hours and by lunch time it was once again only a puff of smoke and a little slower than before. ***????????????

I'm so confused. What could be causing this? I have an airdog so its no fuel issue. Its like the bully dog is constantly in tow safe. If it wasnt worth so much money I would have already tossed this **** out the window on I25.

JCLeary

Do you have a rail pressure gauge? Perhaps your relief valve is shot?

Stainless

Rail pressure I do not have, but how difficult/cost effective is it to try and replace? I'd never thought of that.

ghost24

whats the best version, because i have a boost fooler and crazy larry as well. mine hauls *** but its seems to be tempermental as well...

Stainless

Try adding some pressure, trust me its a whole new world

jrussell

I think it might be the other way around. The ECM sees you're under heavy load and boost is not maxed out, so it would fuel the same or harder to try and compensate. Who knows...just a guess.

Fisherguy

I'm not running either of the Larry programs but I do have a quad boost fooler and am not having any problems using it with my BDTD>
