Just installed my new hallman evolution rx manual boost controller. Looks good, seems to work good. I have the boost right around 20-21 psi. It holds pretty strong as I pull towards redline, but tapers a little. Not like the stock taper, but still a little. Also, in stock form, no boost would be developed while revving the engine in neutral, now with the new controller it develops a little. Sounds pretty cool with the turbo sucking the air in, and the bov letting it go when you lift. Are both of these things normal?

 

no opinions?

 

I didn't see any specific question. You're describing what happens on all turbo cars as far as I can tell...

 

how much of a difference do you feel in the drive with that installed?

 

the main difference was the slight increase in boost and the fact that it holds better as you climb towards redline. As far as noticing a differnce, I really didn't drive it very far. It was really late ,and I took it for a short, really high speed drive. I want to do a little more normal around town driving to really check out the difference. I didn't pay much attention to anything except the boost gauge and the speedo.
