Working with ramping up WGDC early in the RPM range and then scaling down as boost approaches. Did something crazy and reset the RPMs for WGDC high to 0, 2000, 2800, 2825, 3200, etc. Personally, I see no reason for the stock 2200rpm point and the 2400rpm point is just too low. Kept WGDC high (80% EBCS) at 0, 2000, 2800 ... and then immediately dropped to like 40% at 2825. This seemed to work fairly well. I changed the RPM range from 2800/2825 to 3000/3025 since I was still hitting max boost around 3200 or so (which I attribute to the horrible location of the APS catalytic converter). Anyhow, not such a great idea to bump those up by 200rpms. That extra 200 RPMs allowed me to hit 19psi at 2800 and 23psi at 3000. . Good thing for quick acting boost gauges ... my log only has one data point at that pressure so it was clear I acted quickly (the load was 3.61!) However, what concerns me is that the ECU never hit fuel cut even though I have fuel cut set at 20.5psi (down like 3psi from Cobb's high setting).

Long story short ... what I am ending up with is something like this so far ...
0, 2000, 2800, 3200, 3600, 4600, 5600, 6400. The extra control around 4600 seems to be helful with the 11.5lb spring and EBCS. Having a 2800 point gives extra control around where boost is coming on heavy.

^^^ Yep. WDC tables usually look like a big smile The scary thing about the boost cut is that you have to be over your Boost Limit for 1.5 seconds before it cuts (saves) you...

Thanks! You just supplied the missing data I needed. 1.5 seconds. I didn't know that. I was beyond my specific boost-related fuel cut pressure about a fraction of a second so that explains everything.

forgive my stupidity, but why is 19psi at 2800 rpms a bad thing?

Hey wolf, are you noticing any lud BCS noises with your WDC set so high at 0 and 2000rpm? Just wondering if the AP boost control works similar to the Hydras I use to run. Cause I tried what you did and it just made the BCS loud and didn't help??

Nick, 19psi may not be bad given you can tune the fueling and ignition for it, but using a VF-39 and pushing 19psi is much different then say an FP Green at 19psi. I'd be concerned with excess turbo load, heat and detonation. But then again I haven't had a stock turbo forever and it may be tuneable.

It's not. However, in my case, when I was hitting 19psi at 2800 it happened due to spiking ... it was uncontrollable and would spike higher .... i.e. 23psi @ 2000rpms. I have since installed a WG helper spring and now I can hit 19psi at 2800 without spiking. Works like a charm.

No wierd sounds. Mine is mounted to the stock bracket via some sticky mounting pads that allow you to secure things via nylon wire ties. Thus, the stock bracket has it's rubber mounting feet for sound isolation and the plastic mounting pad with it's sticky-tape-side also provides isolation. I don't hear anything.

19 psi is fine for midrange. However, if you read that 19psi during the time when you are spiking and it shoots up to 23psi ... then not good ... rofl.
