James and I are having a hard time getting these injectors to run right. We have tried them on both 3 and 4 bar cals, but the wideband will indicate super lean, 17.8+ intermitently while cruising around, making the car barely runable. I got into higher boost once with the 4 bar map, but the 2 kids in the back seat started yelling to stop, 10 minutes after that the car would lean off the w.b. gauge while cruising and barely run.
Here's a link to them:
