Just completed my engine swap from lb9 to 355 hsr and now the new motor is running very rich. I have already fouled two sets of new spark plugs. I have a custom chip tuned for my configuration. I also have good fuel pressure and am using 22# injectors. I ordered the moates dataloging cable in order to datalog it to send it to my tuner. But in the meantime can I switch out the 22# injectiors with the stock 19# and run the stock chip in order to drive the car to work in the meantime? Or just switch out the chip with the stock chip in the meantime. I really don't wanna have to buy another set of plugs.
Thank you .
