For those who are curious, here is a before and after look at the "PEB Throttle Cut Defender" *edit*
Before the PEBTCD, it took 5.23 seconds to go from 4200-6480. At that time, I was spiking to 16 psi with the MBC and letting X chip control boost the rest of the way. Note that anything about the 16 psi or so I was spiking at would have caused throttle cut at that time.
Now, after the PEBTCD, it takes only 4.51 seconds to go from 4240-6480. I am currently able to spike to about 18 psi and then let X chip control boost the rest of the way.
In Conclusion, before the PEBTCD my car went ~436 rpm/sec and now, after installing the PEBTCD, my car goes ~497 rpm/sec.

Who's gonna do the math... Given XXXX weight, and XXX drag, what's the Horsepower gain?
With the proper assumptions, constant weight and Cd, there should be enough info there to make a change in HP calculation...

That is impressive. I haven't logged in some time, but have you guys...
documented this in any Stage III cars?
I'm asking because I tried at one point to run a MBC in parallel to the N75 (with AWE Stage III) - initially tried it because of some spikes - anyway, when I did, I got throttle cut so I took it out - I think the cut went away - I logged all this some time back....
Just wondering what your experience with this is in a stage III car.....

I'll have to get back to you on that one. I'll let others chime in with their own data :)
As for throttle cut, I can't see how an MBC in parallel could cause such a problem.

I don't know how that is possible either...but, the spikes went away and throttle cut....
started....I took it out and did a few more runs without throttle cut....
I think I need to go do some logging this weekend and see if something might be going on here!
