Well im wondering if i could run a 150 nx wet shot with my stock tuning, so no retarding the timing also i live in california so i run on 91 octane. I really dont want to blow me engine.

 

it shouldn't be a problem.stock timing is usually between 19-25*.it might not be a bad idra to have your afr checked though,you might want to go from a .o33 jet to around a .036 if that is what your kit has stock.mine was 12.7 with a .033 jet so i went up to a .039 to make it 12.0 to be alittle safer.it lost 20 hp but i feel alot more secure now.a scanmaster can check your 02 readings and timing amoung other things.

 

Change your plugs and go for it.For the 150 I would also suggest a walboro intank fuel pump.

won't he need a tune with an aftermarket pump?thats why my racetronix is still not installed yet.with nitrous only the stock pump is more than enough.i have a cam in mine and running 150 and afr is 12.0 at 6200 .it will get weaker before long probably but without a cam on a 150 i wouldn't worry.
