Im planning on only running 3psi untill i can get a tune, as of now i need to finish making my ypipe and then put the timing belt on and then intake and plugs and wires. Then make the down pipe and drain. So im pretty close to getting her finished up but wheres a place to buy a fmu if thatll work for 3psi on a holset hy35. Also im running the maf draw thru is running it blow thru even a good option with the factory maf?
