Any drastic change in injector size is going to need a tune of the ECU.
The ECU just pulses the injector a certain amount of time to inject the fuel.
So if a replacement injector injects more fuel for that given time, it'll run rich as, like you have discovered ;)

i noticed on your sig u are getting a t70 and a new exhaust manifold soon,

i think u should really be getting a after market ecu before u go any further.

yes u need a ecu to run pretty much any injector over 30lb
