What awnsers are you wanting brenden.9? I think its been covered.
Less tehn 5 psi will run on pump premium
No premium available it will blow up, you need torco race fuel concentrate to make up the octane. It has to be that not some gas station crap that makes no difference.
Want more power? Shim the head for 10:1 compression and swap the pullies on the kit for 10-11 psi and it will run on pump premium, same rules apply for lower octane as above.
The kit fits like OEM, can be very reliable.
The downsides? If you dont have premium it will be frustrating to always add and carry torco
Cant say on a nytro but on my apex mpg is a real issue I only get 50-60 good miles before I'm worried about fuel then it will last till arond 80-90 miles on a tank but the last few aren't fun if Im trying to save it and get to a gas stop. I'm adding more fuel capacity to mine this summer.

the stock fuel sys is maxed out at 5 psi on a nytro, a friend tried running his at 7-8 psi with fuel pumpupgrade andstock injectors it would lean out beyond safe, upgrade to mpi blowoff valve,also a good afr guage, vacume/boost guage,and coolant tempguage

okay so if i have to run regular i should lower my boost i wear a backpack so can carry a few bottles. if i do this the plan is mpi stage 1, back country 1 3/4, clutch kit, full exhaust, possibly meth kit, new set of skis don't know what kind???? trail tank. what else do you think i need and a aprrox cost? thanx brendan.
add the cool air intake from mpi, by the time you add in guages,blower,tank,skis and track/drivers, the cost will be up in the 6k+range

I would say shim the head 9-1 instead of 10-1.
work great and fully reliable on premium at 10 psi.

Lower compressoin to at least 10:1 and add water/meth injection and fuel would not be a problem, also keep the boost low.
I'm at 20 lbs running premium fuel, 10:1 CR and meth injection.
