Installed on @David228cx civic and feels way better, the clutch actuation is more precise and there's minimal engine movement when you left the accel pedal. Vibration is more noticiable at low rpm but once the car is moving the increase is minimal. Definitely waiting for mine to arrive and install.
I don't know, usually overboost by a defective wastegate IRC. I don't have the time to have a deeper look right now and also I'm not the expert here. Derek or someone at TSP may take a look at it.
You may want to find yourself as it depends on the traction capability (wheels, temp, surface..) and engine power (tune, response) also how fast you let the clutch and the traction control setup. I found somewhere between 3000 and 4000 ideal for me, but i try to not abuse it as it's hard for the...
All I can say from the feedback of all spanish (spain) users is we love Derek tunes, being the TSP Stage1 or custom e-tune. Can't be wrong with the most experienced tuner on this platform/engine.
CVT can't take much torque, you will have to tune for safe and I think the PRL turbo kit is overkill for this... Is your car and your money tho, do what you want and share the results.
