jb4 g5 map 5
I had the g4 and on map 5 I would get 17lbs with e85. And now with the g5 I only get 13-14lbs. I have the same exact mods. The only thing is that I have 10 set to 800rpm and 12 set to 1000rpm. The car takes longer to spool up but the wastegate rattle is gone. Shouldnt I be getting the same boost?

As to your question it'll boost what it feels it can boost. It'll keep getting higher and higher to a point. You need to do 3 hard pulls in 3rd gear from ~1500-redline and then it'll be ready to go and boosting what it feels it can. From what i've heard the G4 would boost a little higher than the G5. But the G5 seemed to be smoother and overall a bit faster.

I just don't know how you get it to stick. I can go ahead and choose 1, but it won't stick. The lowest i can choose and it will actually keep the value is 2.
Even states this in his guide on his getting started thread.
