Less low end after coming unhooked

So ive had my RN SJ for about 10 months so far, bought it bone stock with a 701 raider motor and carbon reinforced. I have come a long way with mods because lets face it, I got the standup fever and constantly wanted more power. (AM hull is coming soon)

now please don't take me for an idiot who doesn't know anything, just bare with me

Basically if my pump comes unhooked and I hit the throttle it doesn't kick up like it would if the pump was loaded, now obviously this makes sense because the pump now has to load up before it can produce as much thrust. Now here is where my question lays, every time in the past I have read about people doing tricks and what not the phrase "'get the pump unhooked" comes into play. Now I remember hearing that a lot but cant see the reason for wanting to unhook the pump right before a trick, maybe someone can clarify.

Also I ride in the bay where the AVERAGE boat is 35-40 feet, we have a lot of smaller 25 footers and the pretty common 45-65 foot boat that comes by. so you can imagine how choppy it can get at times, if I go to hit a boat wake and its choppy and I come unhooked, if I nail the throttle I basically have to avoid any trick with the lack of thrust.

Can someone shed some light if I should consider a mag pump with my setup.

or possibly my bpipe not tuned for low end enough. other than that if the pump stays hooked up the low end is good but still feel like I'm not getting the full potential of my set up, but carbs seem to be tuned perfect

set up is as follows (only going to list the basic handling and power mods)
Raider 701 62t dual 38s
Dual Cooling
ADA 35cc 180psi head
Factory bpipe ltd with fcv
Lightened Flywheel
Msd Enhancer with oem coil
Stock Ride plate
worx 201 intake
9/15 Hooker
Aluminum pump shoe

That's what I can think of at the moment
With all of these should i look into a mag pump for the choppy water I ride in? if there is a big boat and theres no chop I can hit the wake pretty good but the second my pump unhooks or I try going slow to set up for the wake and I come unhooked I basically have to bail hitting the wake

The mag will help in foamy water that has bubbles in it..and help with hook up. But the pump intake needs to stay in the water. If the water has a lot of wakes in it (rough) or if your approaching multiple wakes from a boat and your ski is on top two wakes and the pump is over the trough it will suck air. Is see this a lot, bigger wake is behind some smaller ones that are real close together.

On your other question, normally it's berry the pump before the trick or get the pump loaded, before the trick. Also get the pump unhooked when slidding the ski around in a turn involved in or before a trick

Thank you for the response and as for the pump getting loaded before I understand, but if I unload the pump then bury it and hit the throttle I still don't have that response, do I need more time for my pump to load up before I launch?

Never heard of unloading a pump them load the pump before the trick... But yes if your doing that it needs more time to reload

Was talking about this the other day. Not sure why but my best flips come from when the ski feels like the pump unhooks and then hooks up again. Usually this happens to me after a really big blip before a flip. Not sure what is actually going on but does feel as though the pump is coming out of the water a bit. Maybe it lets the pump spin up and have the motor Rev up quicker so when you pull the throttle off the ramp the motor is in the top rpm range where the power is?

Obviously this is only slight unhook, because if you get out of the water too much and nothing in the pump when you return it won't do anything for you. I'm sure some of the pump and riding experts on here knows the real answer but I have had it happen on my boat and didn't know why it worked well, I just knew I liked the results
 
so would it be worth it if I got the solas mag 144, I do ride a lot and mainly freestyle just not sure. basically I haven't bought a mod in a while and I'm due hahah
its either I go with the mag pump or I go a new steering system route, which I don't think I need right away

What is your goal here. You said you want an AM hull right? So I assume you want to flip? Do you ride ocean or lakes, flat water or boat chase? Sounds like you boat chase and sometimes messy water. But you said AM hull coming soon. If you are truely going to change to an AM hull soon don't waste the money on a solas144 mag. Wait till you get an AM hull and get a 148 or even a 155 (155 OEM if on a budget especially with your small CC motor)

Honestly modding out your SJ is going to do nothing for you if you want to change to an AM hull. Save your money and shop for the other hull. Till then learn the basics on your SJ. Footholds, steering, bpipe, prop. After that the rest seems as tho of a waste as for what that will do for you on a SJ hull. The little things come into play with the AM hull when you have the money, but if you want to be doing more than a 180nose stab or a barrel roll then its the hull holding you back and spending money on the pump and little things will only disappoint. Just my opinion, someone will differ. I ride an AM ski and never go back to OEM, someone might be the opposite rider and tell you to mod the hell out of the superjet. Sounds like if you have boat wakes and the desire for a AM hull then save your money for that... Good luck

Thank you for the response and I do want to go am hull soon but also plan on keeping my sj.
And yes I do want to flatwater flip one day but for the time being I'm on a bay with big boats and ocean rides.
Now yes I can find an am hull tomorrow and buy it or find one months from now so wanted to make the best of the time before my am hull haha
