If it was sat right the way open surely it'd take a while to hit 0psi from vacuum? It shoots straight up to 0psi pretty much as soon as you step on the loud pedal. You're still on the standard 200sx turbo arnt you? As thats what im using at the moment, it should hit boost at 2700ish iirc?
Considering I havnt burnt this thing to the ground yet, I think I deserve a f**king medal :/
Not so sure, I'm on 1.2 bar on the T28 so it's a bit laggier. Spools up from fairly low down though.
The wastegate is so small that I reckon it could jump straight out of vacuum. The merest of throttle prods will make .3 or more boost straight out of vacuum according to my Profec B. Worth checking the linkage hasn't seized if the boost controller is fine anyway.
