How does it feel when accelerating at partial throttle? Can you get it to start boosting at moderate RPM and throttle position? In other words, can you get a bit of assist during casual acceleration?

How about giving it a bit more throttle, and then letting it go (not completely) when boost starts to kick in? In other words, give it a decent amount of throttle to 40mph, and slightly releasing it and coast.

How about getting in 3rd, progressively press down the pedal to the floor, let boost kick in, and then gradually release the pedal and coast?

How about making a turn. Have you guys hit boost while turning and applying throttle? Does it oversteer easily because of this? It happened when I drove the Z32-TT... got a bit happy, squirrelly, but quite fun overall.

Also, with a boost controller like the EVC6, how well does it improve response especially at varying throttle position, RPM, etc. compared to not having one at all?
I will try to do my best to asnwer most of your questions.

1. When accelerating at partial throttle it really all depends on what gear your in. My boost normally kicks in around 3-4k rpm. So with that being said you can get very good assistance from partial throttle.

2. Im not sure what your really asking here but when you first get on it and slowly let off the car is smooth. However suddenly dropping the gas to slow down and can a bit jerky under boost.

3. You have to be careful around turns in boosted cars. Plenty of times I go to get on it around a turn and the rear comes loose a little. Boost is tricky with our cars and spools quick and hard so it catches you by surprise.

4. Again I am a little confused on what your really wanting to know but having a boost controller only really controlls boost levels. rpm have a effect on boost but i can slowly bring my rpm's up and not really be in boost but the second I hit the floor the car freaks lol.

All in all I hope I answerd some of your questions.
