Well, none of the other cars (including yours) had that problem.
I'm thinking that the PCM might be adding fuel when it thinks the vehicle is standing still.
Though, that probably isn't likely.
The other possibility is that it just heat-soaked on that dyno like Todd's did.
Either way, it can't hurt to trick the DSC.
When I have it in next, I'll log the intake and coolant temps.

take your whp graph, pick some points and plot them in excel, you can get your torque that way.

You need to know your gearing for that to work, BTW.

I wouldnt think thats the case, because so many 8s, 8s running boost, 8s running boost with various different Engine Management Systems... haven't had that problem.

No. Its nasty. It isn't even really a bumper - its just an applique that is attached to the OEM bumper after cutting a chunk of it off.
It just looks dumb to me, anyway. Like a fake diffuser.

BOO!!!

You forget, the MS Rear causes spontaneous break dancing, and by touching it (even through the shield of a towel) it has been known to provide a very "orgasmic" experience.

If I could sport that kind of headgear without looking stupid, I'd rethink my position.

uncontrolable instant break-dancing is never a good thing!

im sure we can find a turban that works for you. Displayed there is the Industrial Turban. Other popular choices are the Corporate Turban, Surf Turban, and Urban Turban. All becoming available in the near future....

Break dancing



Why would losing spark cause the boost to fall off?

I dunno, no spark (combustion) usually causes lots of things to "fall off" :P

It was completely street-tuned. Hence its perfect performance on the street and lack thereof on the dyno.
Hopefully, they have received their inductive pickup at the shop so I can bring it in this week.

That was going to be my point...turbo cars are so picky...get it tuned on the dyno and you'll be breaking up driving it on the street...this is why I stick NA....ok ok its because i'm too afraid to put a turbo in a 30k car...don't wanna know ill be blowing my engine

I've turbo'ed pretty much every car I've ever owned. Each is a unique experience, but they aren't "picky" - variation and incompatibility issues are just part of the process. Eventually, the vehicle will perform equally well in all situations just as it did in its OEM state of tune.

So, to a word, your point is completely incorrect and irrelevant.
