Hey everyone,I just finished swapping in a stock rebuilt kade engine (blew piston #1 originally) and need some help. Before the swap, I was running a JWT n/a ecu tuned for 370cc injectors and had a FMU installed on a T3/T4 setup and the car idled fine. I just swapped the engine and now using a JWT turbo ecu tuned for 370cc injectors and stock MAF and the car sputters & boggs at idle (removed FMU). All engine internals are stock right now!Any help is greatly appreciated!

You got a wideband? Have you checked your timing? What is your spark plug gap at? What is your fuel pressure at?

I don't have a wideband yet and haven't check the fuel pressure yet, but will soon. I am also about to wire up my SAFC as well. I gapped the plugs at .032 ... What should the fuel pressure be at?
