After filling the car up with v power there is a noticeable difference in the performance of the car, I can only assume it had premium in it.

But the thing is on a standard car would there be any noticeable difference ?
I bought it as standard bar a k and n panel filter, once gtr is home think I need to get the vbox in it to verify 0-100 mph time, stock is 8.7 seconds, stage 1 should I think be into the 7s.
Need to check before I drive 100 miles just to end up being charged to be told it's stage 1 anyway lol
