i'm thinking of stacking my VA3.1 with the BDDL....will this stack be ok??????

 

nobody knows

 

I recall AK having said that the C3.2 (the duration box) is the one that stacked great with the BDDL. Ck with him. I know he ran both of these boxes.

 

Anything will stack with the BDDL because it is a downloader.

The VA C3.1 will provide extra fueling downlow from pressure and taper off ontop. It might be a really nice stack...especially for the tow crowd or those wanting more down low. I would try it on the Mid BDDL setting first.

 

thanks everyone

 

I don’t see how I missed this thread earlier.

I played with the BDDL and the VA C3.2 duration box, not the pressure box. The BDDL on Extreme and the VA C3.2 on 50% was the best combination. The VA takes what it sees, not knowing what it is being given, and stretches it by the amount it has programmed inside. With the BDDL loaded, it is already stretching duration from within, so what you end up with is the VA is stretching an already heavily stretched injection event…..compounding effect. BDDL on Extreme and VA on 50% was a very strong, hard pulling stack and ran well. Cranking the VA up to 100% yielded much smoke, power was insane, but the engine just didn’t sound like it was enjoying it. I only assume, but I bet that was an extremely long injection event, much longer than what is healthy.

For what its worth, the BDDL on the performance setting and the VA on 100% ran pretty good, but I think the Extreme program and 50% VA was stronger and cooler running.
