Fly Hi

[Infinite Power]

I have a move that has a character flying for a certain amount of time, but I can't fly up to hi, how would I change this move so I can fly for a longer time and fly higher.

here is the move-

;---Being Carried---
[Statedef 1510]
type=A
physics=N
movetype=I
anim=1510
ctrl=0
velset=0,0
sprpriority=-2

[State 1510, timer]
type=varadd
trigger1= 1
var(46)=-1
[State 1510, fall]
type=changestate
trigger1= var(46)<=0
trigger2= roundstate!=2
value=1590

[State 1510, Turn]
type=turn
trigger1= p2dist x<0

[State 1510, Pos]
type=posset
trigger1= pos y>200
y= -100
[State 1510, Pos]
type=posset
trigger1= pos y<-301
y= -300

[State 1510, Vel]
type=velset
trigger1= 1
x=0
y=sin(gametime/16.0*pi)*0

[State 1510, Vel]
type=velset
trigger1= command="holdfwd"
x=2
[State 1510, Vel]
type=velset
trigger1= command="holdback"
x=-2
[State 1510, Vel]
type=velset
trigger1= command="holdup" && pos y>-125
y=-2 + sin(gametime/16.0*pi)*.5
[State 1510, Vel]
type=velset
trigger1= command="holddown" && pos y<-3
y=2 + sin(gametime/16.0*pi)*.5

[El Chupacabras]

[State 1510, Pos]
type=posset
trigger1= pos y<-301  <----- Make this value lower.... LOWER.
y= -300  <---- And this one as well respectively.

[Infinite Power]

El Chupacbras I have trie lowering both of those numbers the first one i LOWERED, and when I do the character either takes off in flight height to fast or I'm only able to control the character x- axis in the air. how would I set this up so I could fly as high as a super jump but still be able to control flight movement around like the normal move?
