four stroke needs to have the throttle wide open or it will come up short on psi. most engine builder cc the head.
Having the throttle open is also not necessary (contrary to popular belief). Done it both ways and there's no difference.

so just so there is no confusion, on two strokes havin the throttle open does not make a big difference when doin a comp test. on four strokes it makes a big difference, it will come up vary short on psi if the throttle is not wide open.
I have a 50 with 60 carbs currently and am wanting to swap to the 60 tuner(part number 8m0045214) and modify it like I've read about here, does anyone have specifications of exactly what they did to theirs? Will there be any fitment issues on my 50?
Its the same, except at the top where it vents.
So it wouldn't be worth changing? Or are you saying it will fit fine?
no,,, work on the one u have. the 60 will fit yours fine, but its no different than the one u got now,(sizes wise).
