I agree with the BDEL table. The example I gave in the screenshot was with a slower spooling turbo than stock.
Every car takes a slightly different approach to tuning the tables. Solenoids, wastegate actuators, actuator tension, cams, mivec settings, etc. The general idea is the same for all though.

I prefer I slight difference in spool in higher gears at low RPM then possible overshoot in varied situations. My outlook is if you are spooling a turbo at 2500 in 5th gear you aren't out trying to break any records. Every tuners method is slightly different. Doesn't make either right or wrong.

The WGDC is reduced automaticely by this value (62-1=61)
At 2500 RPM you see below 94% WGDC but this value raise by 2 at WOT to 96%. Of course, for maximung spool-up you have to set her the value 98 in the table but in winter and in the highest gear it is too radical.
It is huge advantage to fill in some additional values between 2500 and 3000 RPM in order to brake down the spooling speed softly and with allmost no WGDCC and less spiking.
With this setting you will reach around 22.5 Psi at 3000RPM and at redline there are aorund19 PSI.

What all tables are rescaled by rescaling the BDEL/MWGDC tables to have nothing below 2000RPM? I'd like to get rid of the first useless values in mine but I don't want to miss any other scaled tables. Also, does anyone know if you rescale the RPM axis in the standard maps will it rescale it in the tephra style switched maps also?
Yeah, but do you actually see it drop your wgdc by 1% at 63%TPS when logging, or does the ecu have a floor of 0 where it won't actually lower anything there?

andrewzaragoza - I apologize if i was confusing with my post... Bryan is correct, I am going to replace my current #65 pill and boost assembly with this Tactrix unit. I don't have an issue with the boost assembly that I purchased off GST, in fact it has worked great for me so far. But it seems that I might be able to hold higher boost up top AND have better spoolup with this solenoid. Sounds like a win-win to me

subscribed for your results homwerk. I'm currently in the same situation as you, my boost pill is working fine, but trying to determine whether it's worth it to switch. I'm not looking so much for higher boost as I am more interested in boost response or responsiveness to changes in wgdc.

What are you guys doing for race gas tunes? This would be for drag racing where I don't see my peak tq rpm ever...
Tonight I left my desired load where I had it for the street/race gas tune (in the 300's) then set my base wastegate all to 100's to get all the boost I could.
My max boost over the 1/8th mile was 29.8 I believe. Is there any way to get it to go any higher or is this limited to something mechanical and or the turbo? I do need to check on some fp green info to see I'm just crazy thinking it could hit 30-32psi.

I crushed my Evo 9/JDM bov the other day and saw 33psi at 4500 around 70% wgdc. (error correction had kicked in and pulled approx 10% duty cycle)
I had to bring it down to around 65% to get 29psi.
33psi was around 330 load.
This is on a GM 3 port and a stock Evo 9 actuator. FPgreen, All unported bits (turbo/stock 02/exhaust manifold)
Held about 24 psi at 7k at around 98% duty cycle
