running rich
I have a 91 1.6 with a greddy internal waste gate kit with 1.8 injectors and a fuel pressure riser im not pushing over 5psi.. yet. but i seem to run a bit rich at half throttle. would the 02 clamp help run with less fuel at low rpm?

Clamp won't help with being rich, o2 clamp helps fool the stock ecu into not seeing the rich condition in boost and pulling fuel. If anything, on the low end, your stock ecu should be trying to pull fuel if you are running that rich. GReddy kit in stock form runs rich for safety as it is so adding the 1.8 injectors as well probably doesn't help either. I'm assuming that the fuel pressure riser you refer to is the blue Vortech one from the GReddy kit?

No the one i have is black and a different shape. i added the bigger injectors because i had a little predetonation.
