welp i finally figure out what was causing the hesitation at 4000 rpm's. Thanx to alot of you guys/gals, my actuators werent opening right so i took them off and bingo my hesitation is gone. I wired them open, now is this gonna cause any other problems if i dont replace my actuators and run them open all the time? thanx again.

you will have a lot less power under 4k rpm, but its not going to hurt anything. and if you want to go fast you will be above 4k anyway.

 

I feel no difference in power below 4000 rpm's, seem fast above 4000
