My motor is pig rich as well, but i can’t double the factory boost and stay safe. Granted 7 lbs is nothing, so doubling that isn’t too bad i guess. Some SRT-4 guys use map clamps (caps voltage that ecu sees to lean out the a/f mix for more power), but with the Mr2 i wonder if the factory fuel system can safely compensate for twice the boost. Running rich on 7lbs is safe, but what will his a/f be at 14psi? Something just doesn’t add up to me.
