yea gears make no difference, the guy just decided to run it in 5th, guessing to maybe avoid wheel spin and get a clean run
as for responsiveness, it isn't great, but im used to it, and once it passes around 4000rpm, it pulls like a fkin steam train. Haven't really paid much attention to the boost gauge, just the tacho, seeing peak power is made so damn high up in the rev range, with a dead stock top and bottom end, so i couldn't really tell you when full boost is reached, suppose i could check tomorrow
To be quite honest, im kinda dissapointed, i want MORE!
