Default Perrin EBCS & Boost Map

For those of you who are using Perrin's EBCS, what kind of changes did you need to make to your boost map values? The instructions say 30% reductions for interrupt mode (which I'll be using) - are these accurate? What about changes to the Gain (as if spool can be too quick )?

Mods (just in case it matters):
Drop-in Filter
Samco IC hoses
HKS Replica Header
Helix Uppipe
Madad V1 Shorty downpipe
Prodrive ABE

I use the GM solenoid, basicly the same as the EBCS.
You will need to raise you gain a couple of points to reduce spiking. I would start with ~150 in the boost map and work your way up in steps ~20. When you start to see the boost rise with the map #'s reduce your steps to ~10. Once you start to control the boost with the new solenoid the #'s in the boost map become more sensitive.

Yours had instructions?

Percentage wise I'm not sure. I knew it was coming though. I dropped everything in my boost map by 100 and worked upward.

I didn't have to work up very far.

Just make sure you drop them down to something. I shiver when I think of what would have happened with the EBCS and my old map...

Yeah, the scientific inquisitive part of me wants to datalog boost pre EBCS, post EBCS (same map), & post EBCS (revised map). I think it would be an interesting comparison. But the part of me that doesn't want to hit fuel cut & do bad things to my motor isn't so keen on the idea. Maybe I'll cut my boost values in half just to run the comparison.

If you want to run a low boost comparo. Up the boost #'s until you get jusy over wastegate pressure. That way the solenoid is controlling boost and not the wastegate.
