First off change your damn ecu.. you probably got the wrong ecu and pappi is right your car is in limp mode for w/e reason make sure your car doesn't have a chipped ecu wrongly or possible also check all your grounds.. should have spent that money on a b series swap anyway.

 

also your cam timing might be off man and if it is your bending some valves.. i hope your not you need to go threw a check list on your car starting with your grounds, then your hoses and belts then your timing and wires, then your ecu man.. gl with it.
